[Done] a) A back titration is implemented in indigestion and constipation remedy analysis using a milk sample. A magnesia milk sample weighing 3.964 g and containing magnesium hydroxide, Mg(OH)2, was added to 60.00 mL of 0.350 M hydrochloric acid (HCl) in a conical flask. After the reaction was completed, the excess HCl in the conical flask required 30.45 mL of 0.216 M sodium hydroxide (NaOH) for titration to achieve the end point. Calculate the percentage (w/w) of the active ingredient Mg(OH)2 in the sample. The reaction: Mg(OH)2 + 2HCl → MgCl2 + CO2 + H2O b) Distinguish between end point and equivalence point.
