Maganite is the leading brand for antacid to alleviate heartburn. Its active ingredient is a saturated solution of magnesium hydroxide (milk of magnesia) which neutralizes the sudden increase of H+ during heartburn. Its manufacturing company performed microtitration to simulate how the drug works upon intake.A 50.0 mL saturated solution was prepared. After filtering each solution, a 5.0 mL aliquot was transferred to a 25.0 mL Erlenmeyer flask and was titrated using pre-standardized 0.0320 M HCl which resembled the gastric acid. The endpoint was reached after the addition of 52.2 μL titrant.1. What is the concentration of hydroxide ions in the solution? Note: Use the scientific notation of 0.00012 = 1.2e-4 2. Determine s and Ksp of Mg(OH)2.Note: Use the scientific notation of 0.00012 = 1.2e-4

TOPIC: Recrystallization Students were tasked to conduct a recrystallization experiment to test the ability of the three newly discovered solvents in their laboratory to purify and separate a mixture containing compounds X and Y. The solubilities of the two compounds in g/50 mL of hot and cold solvents are given in the table. Given the data, if a mixture containing 9.0 g each of X and Y is to be recrystallized from 100 milliliters of the solvents, what is the best solvent to use? Support your answer by doing a schematic diagram for EACH solvent.
