Macmillan Learning A. What is the pH of an aqueous solution with a hydrogen ion concentration of [H+] = 2.9 × 10-7 M? pH = 6.53 B. What is the hydroxide ion concentration, [OH-], in an aqueous solution with a hydrogen ion concentration of [H+] = 2.9 × 10-7 M? [OH-] = ×10 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+] = 4.00 × 10+ M, and [A] = = 4.00 x 10 M. Calculate the K₁ value for the acid HA. Ka = ×100 ×10 TOOLS M
