MEASURING pH - Lab Report Example The addition of Rolaid solution was carried out in increments of 10 mL to a maximum of 30 mL of Rolaid solution in soda. pH of the resulting solution was measured at each addition of the Rolaid solution using a pH meter. For the second titration run, the diluted lemon juice solution was gradually added to the milk. The addition of lemon juice solution was carried out in increments of 10 mL to a maximum of 30 mL of lemon juice solution in milk. pH of the resulting solution was measured at each addition of the lemon juice solution using a pH meter. Q 1. As more and more antacid is added to the soda, the pH tends to increase. The relationship between antacid and soda shows an increasing trend. The increase in pH is greater at the beginning but tends to taper off to approach a plateau. Q 2. As more and more lemon juice solution is added to the milk, the pH tends to decrease. The relationship between lemon juice solution and milk shows a decreasing trend. The decrease in pH is nearly constant overall leading to the conclusion that the relationship is linear. Q 3. As more and more lemon juice solution is added to the milk, the milk tends to curdle more and more. The constant decrease in pH indicates that the lemon juice is causing curdling and a net decrease in the amount of hydrogen ions in solution. Q 6. A buffer contains both hydrogen ions and hydroxyl ions though in weak concentrations. When an acid is added, the buffer solution consumes the hydrogen ions to keep the pH constant. When an alkali is added, the buffer solution consumes the hydroxyl ions to keep the pH

Judaism - Essay Example Although Jews resemble Christians in many ways, they are not confined to pray or worship in one area or room like the Christians. They believe that God dwells among people and not in a specific place. In addition to that, Jews are more independent and do not relate or reference with any other religion like the Christians relate to them. Although the Christians continuously reference to the Jews customs and traditions, Jews have remained independent do not borrow or copy practices from other religions (Valkenberg, 34). In conclusion, it is clear that Christianity and Judaism have a lot of similarities. However, there are also a lot of differences between the two uniquely similar religions. Judaism is both a â€Å"peoplehood† and a religion while Christianity is basically a religion. With this in mind, it is evident that though Christianity and Judaism have a lot of similarities, the differences that exist cannot be settled until the coming of Christ as stated in the Bible and Torah (Valkenberg,
