all put on our safety goggles before gathering our materials. Step 2- We gathered our 4 petri dishes and labeled them using a grease pencil. One petri dish labeled “C” for Control‚ “V” for Vinegar‚ “A” for Ammonia and “B” for Bleach. Step 3- Once the petri dishes were labeled‚ we took a 25 ml cylinder and used a pipette to gather 12 brine shrimp to put inside of the cylinder. Using the measurement lines on the side of the cylinder‚

calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange‚ the volume of sodium hydroxide used is taken down. After doing some calculations‚ the average percentage of calcium carbonate in toothpaste is 19.2%. This average percentage is relatively close to the expected percentage of 20% thus

Group no.4‚ 2D-Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Recrystallization is a method for purifying solid organic compounds. The process is dissolving the solid to be purified in a hot solvent and cooling the solution slowly‚ this allows impurities with different solubility to separate from the solution in each step. The objective of the experiment was to synthesize acetanilide by the acetylation
