B. What is the hydroxide ion concentration, [OH-], in an aqueous solution with a hydrogen ion concentration of H*] = 4.6 x 10-³ M? 11.7 [OH¯] = M Incorrect 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] = 0.270 M, [H*] = 4.00 × 10-4 M, and [A-] = 4.00 x 10-4 M. Calculate the K value for the acid HA. 2.86 x10-7 Ka = Incorrect
