4. You were calculate the magnesium hydroxide as there antacid of choice. (10) performing an antacid lab and provided the following data from your class mate. Help them the missing information in the results table. Show all work below. The student choice to use Concentration of HCl 0.511 M Concentration of KOH 0.508 M Mass of Antacid Tablet1.2568 Volume of HCl added 25.00 mL Volume of KOH titrated 8.05 m Mole initial acid Results Table Moles HCl excess Moles HCI neutralized Moles of Antacid Mass of Antacid % Antacid 0.01278 moles 3. The table below contains conductometric titration data for the following precipitation reaction: created from 5.85 mL of sodium chloride diluted to 10.56 mL with distilled water solution and titrated with silver nitrate. The NaC concentration utilized is 0.506 M. Determine the equivalence point, explain your reasoning with mathematics or written proof.
