A. What is the pH of an aqueous solution with a hydrogen ion concentration of [H+]=8.5107 M?

pH=

B. What is the hydroxide ion concentration, [OH], in an aqueous solution with a hydrogen ion concentration of [H+]=8.5107 M?

[OH]= ? M

C. A monoprotic weak acid, HA, dissociates in water according to the reaction HA(aq)H+(aq)+A(aq)

The equilibrium concentrations of the reactants and products are [HA]=0.290 M, [H+]=2.00104 M, and [A]=2.00 104 M. Calculate the a value for the acid HA.
