Stoichiometry
A titration analysis was done to determine the arsenic acid (H3AsO4) content of an impure sample. The titrant used is a 0.454 M NaOH solution. a. Give the balanced equation of the reaction. (Hint: consider arsenic acid to fully dissociate; H3AsO4 → 3H+ + AsO43-) To prepare the analyte for titration,...
