Problem

− is a weak base. Which equilibrium corresponds to the equilibrium constant  a for HA?

A)  A (aq)  +   OH (aq) ⇌  HOA 2−(aq)

B)  HA(aq)  +   H 2O(l) ⇌  H 2+(aq)  +  OH − (aq)

C)  HA(aq)  +   H 2O(l) ⇌  H 3+(aq)  +  A (aq)

D)  A (aq)  +   H 2O(l) ⇌  HA(aq)  +  OH (aq)

E)  A (aq)  +   H 3+(l) ⇌  HA(aq)  +  H 2O(l)
