In 0.100 M HC₂H₃O₂(aq), [H₃O+(aq)] = [C₂H₃O₂^-(aq)] = 1.3 x 10^-3 M. If a few drops of concentrated HCl(aq) are added to this solution, the C₂H₃O₂^-(aq) concentration is: A) 1.3 x 10^-3 M C) = 1.3 x 10^-3M D) 0.100 M

Question

In 0.100 M HC₂H₃O₂(aq), [H₃O+(aq)] = [C₂H₃O₂^-(aq)] = 1.3 x 10^-3 M. If a few drops of concentrated HCl(aq) are added to this solution, the C₂H₃O₂^-(aq) concentration is: A) < 1.3 x 10^-3 M B) > 1.3 x 10^-3 M C) = 1.3 x 10^-3M D) 0.100 M

Quizplus · Accepted Answer

The Answer is A

In 0100 M HC2H3O2(aq), [H3O+(aq)] = [C2H3O2-(aq)] = 1

In 0100 M HC₂H₃O₂(aq), [H₃O+(aq)] = [C₂H₃O₂^-(aq)] = 1
