Question

A. What is the pH of a solution of 40.0 mL of 0.100 M acetic acid (K_a = 1.8 x 10^–5) after 50.0 mL of 0.100 M NaOH has been added?

B. A particular saturated solution of silver chromate (Ag₂CrO₄), has [Ag⁺] = 5.0 x 10^–5 M and [CrO₄^2–] = 4.4 x 10^–5 M. What is value K_sp for silver chromate?
