PH Lab Report Essays PH Lab Report Paper PH Lab Report Paper Soapy water Material Required To facilitate this laboratory exercise, the experimenter needs the following: pH strips Sample reservoirs of solutions with varying pH Laboratory Notebook pH paper Background H stands for potential hydrogen. This is a measure of the acidity or basilica of a solution. Acidic and basic are two extremes that describe a chemical property chemicals. Mixing acids and bases can cancel out or neutralize their extreme effects. The pH scale is a set of standard solutions whose pH is established by international agreement. A substance that is neither acidic nor basic is neutral. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten mimes more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline than the next lower whole value. For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8. Primary pH standard values are determined using a concentration cell with transference. This measures the potential difference between a hydrogen electrode and a standard electrode. Measurement of pH for solutions can be done with a glass electrode and a pH meter, or using indicators. PH measurements are important in medicine, biology, chemistry, environmental science, oceanography, etc. Procedure For each of the samples you selected, execute the following steps to acquire the PH. . Cut a strip of pH testing paper utilizing the serrated edge of the dispenser (1-2 in. Length minimum). 2. Submerge the pH testing strip and immerse in solution for approximately 10 seconds. 3. Remove the strip and promptly compare the results to the specimen colors indicated on the dispenser. 4. Record data for the tested solution. 5. Repeat the steps until you have tested all solutions. Data Solut ion Name Personal pH Recordings Group 2 pH Recordings Group 3 Recordings average H Recordings . Soda Orange Juice 3. Iced Tea 6 4. Lime Juice 3 4 5. Water 7 6. Milk 7. Soapy Water 8 Conclusion In concluding this lab I found that, in general most groups had similar recordings in their lab. Although, when testing the pH of soda the recording of pH between groups ranged from 1 to 3. A 3 on the pH scale is 100 times more acidic than a 1. The recording did not change much from my earlier predictions. In the beginning of the lab I anticipated that the order of the solutions tested old be in the following on a pH scale: lime juice, orange juice, soda, iced tea, milk, water, soapy water. This was correct aside from the fact that soda is before orange juice on the pH scale. This is less surprising when reviewing the amount of acid in soda. Acid is listed on average in three forms on a nutrition label for soda. If I were to conduct another lab on pH would test if the level of pH differs from soda brand to soda brand. Overall, the lab familiarized me with the concept and meaning of pH and gave me experience in measuring it, therefore accomplishing the purpose.

Anne Boleyn Biography, Facts, and Background

Anne Boleyn Biography, Facts, and Background Anne Boleyn Facts Known for: her marriage to King Henry VIII of England led to the separation of the English church from Rome. She was the mother of Queen Elizabeth I. Anne Boleyn was beheaded for treason in 1536.Occupation: queen consort of Henry VIIIDates: probably about 1504 (sources give dates between 1499 and 1509) - May 19, 1536Also known as: Anne Bullen, Anna de Boullan (her own signature when she wrote from the Netherlands), Anna Bolina (Latin), Marquis of Pembroke, Queen Anne Also see: Anne Boleyn Pictures Biography Annes birthplace and even year of birth are not certain. Her father was a diplomat working for Henry VII, the first Tudor monarch. She was educated at the court of the Archduchess Margaret of Austria in the Netherlands in 1513-1514, and then at the court of France, where she was sent for the wedding of Mary Tudor to Louis XII, and remained as a maid-of-honor to Mary and, after Mary was widowed and returned to England, to Queen Claude. Anne Boleyns older sister, Mary Boleyn, was also at the court of France until she was recalled in 1519 to marry a nobleman, William Carey, in 1520. Mary Boleyn then became a mistress of the Tudor king, Henry VIII. Anne Boleyn returned to England in 1522 for her arranged marriage to a Butler cousin, which would have ended a dispute over the Earldom of Ormond. But the marriage was never fully settled. Anne Boleyn was courted by an Earls son, Henry Percy. The two may have secretly been betrothed, but his father was against the marriage. Cardinal Wolsey may have been involved in breaking up the marriage, beginning Annes animosity towards him. Anne was briefly sent home to her familys estate. When she returned to court, to serve the Queen, Catherine of Aragon, she may have become embroiled in another romance this time with Sir Thomas Wyatt, whose family lived near Annes familys castle. In 1526, King Henry VIII turned his attentions to Anne Boleyn. For reasons which historians argue about, Anne resisted his pursuit and refused to become his mistress as her sister had. Henrys first wife, Catherine of Aragon, had only one living child, and that a daughter, Mary. Henry wanted male heirs. Henry himself had been a second son his older brother, Arthur, had died after marrying Catherine of Aragon and before he could become king so Henry knew the risks of male heirs dying. Henry knew that the last time a woman (Matilda) was the heir to the throne, England was embroiled in civil war. And the Wars of the Roses had been recent enough in history that Henry knew the risks of different branches of the family fighting for control of the country. When Henry married Catherine of Aragon, Catherine had testified that her marriage to Arthur, Henrys brother, was never consummated, as they had been young. In the Bible, in Leviticus, a passage forbids a man from marrying his brothers widow, and, on Catherines testimony, Pope Julius II had issued a dispensation for them to marry. Now, with a new Pope, Henry began to consider whether this offered a reason that his marriage to Catherine was not valid. Henry actively pursued a romantic and sexual relationship with Anne, who apparently held off from agreeing to his sexual advances for some years, telling him that he would have to divorce Catherine first and promise to marry her. In 1528, Henry first sent an appeal with his secretary to Pope Clement VII to annul his marriage to Catherine of Aragon. However, Catherine was the aunt of Charles V, the Holy Roman Emperor, and the pope was being held prisoner by the emperor. Henry did not get the answer that he wanted, and so he asked Cardinal Wolsey to act on his behalf. Wolsey called an ecclesiastical court to consider the request, but the Popes reaction was to forbid Henry from marrying until Rome decided the matter. Henry, dissatisfied with Wolseys performance, and Wolsey was dismissed in 1529 from his position as chancellor, dying the next year. Henry replaced him with a lawyer, Sir Thomas More, rather than a priest. In 1530, Henry sent Catherine to live in relative isolation and began to treat Anne at court almost as though she were already Queen. Anne, who had taken an active role in getting Wolsey dismissed, became more active in public matters, including those connected with the church. A Boleyn family partisan, Thomas Cranmer, became Archbishop of Canterbury in 1532. That same year, Thomas Cromwell won for Henry a parliamentary action declaring that the kings authority extended over the church in England. Still unable to legally marry Anne without provoking the Pope, Henry appointed her Marquis of Pembroke, a title and rank not at all usual practice. When Henry won a commitment of support for his marriage from Francis I, the French king, he and Anne Boleyn were secretly married. Whether she was pregnant before or after the ceremony is not certain, but she was definitely pregnant before the second wedding ceremony on January 25, 1533. The new Archbishop of Canterbury, Cranmer, convened a special court and declared Henrys marriage to Catherine null, and then on May 28, 1533, declared Henrys marriage to Anne Boleyn to be valid. Anne Boleyn was formally given the title Queen and crowned on June 1, 1533. On September 7, Anne Boleyn delivered a girl who was named Elizabeth both her grandmothers were named Elizabeth, but its commonly agreed that the princess was named for Henrys mother, Elizabeth of York. Parliament backed Henry by forbidding any appeals to Rome of the Kings Great Matter. In March of 1534, Pope Clement responded to the actions in England by excommunicating both the king and the archbishop and declaring Henrys marriage to Catherine legal. Henry responded with a loyalty oath required of all his subjects. In late 1534, Parliament took the additional step of declaring the king of England the only supreme head on earth of the Church of England. Anne Boleyn meanwhile had a miscarriage or stillbirth in 1534. She lived in extravagant luxury, which didnt help public opinion still largely with Catherine nor did her habit of being outspoken, even contradicting and arguing with her husband in public. Soon after Catherine died, in January 1536, Anne reacted to a fall by Henry in a tournament by miscarrying again, at about four months into a pregnancy. Henry began speaking of being bewitched, and Anne found her position endangered. Henrys eye had fallen on Jane Seymour, a lady-in-waiting at court, and he began to pursue  her. Annes musician, Mark Smeaton, was arrested in April and was probably tortured before he confessed to adultery with the Queen. A nobleman, Henry Norris, and a groom, William Brereton, were also arrested and charged with adultery with Anne Boleyn. Finally, Annes own brother, George Boleyn, was also arrested on charges of incest with his sister in November and December of 1535. Anne Boleyn was arrested on May 2, 1536. Four men were tried for adultery on May 12, with only Mark Smeaton pleading guilty. On May 15, Anne and her brother were put on trial. Anne was charged with adultery, incest, and high treason. Many historians believe that the charges were created, likely with or by Cromwell, so that Henry could get rid of Anne, marry again, and have male heirs. The men were executed on May 17 and Anne was beheaded by a French swordsman on May 19, 1536. Anne Boleyn was buried in an unmarked grave; in 1876 her body was exhumed and identified and a marker added. Just before she was executed, Cranmer pronounced that the marriage of Henry and Anne Boleyn was itself invalid. Henry married Jane Seymour on May 30, 1536. The daughter of Anne Boleyn and Henry VIII became Queen of England as Elizabeth I on November 17, 1558, after the deaths of, first, her brother, Edward VI, and then her older sister, Mary I. Elizabeth I reigned until 1603.
