- a. {CO_3^2-} = M
- b. {Na+} = M
- c. {HCO_3^-} = M
- d. {OH^-} = M

(Enter your answer in scientific notation.)

## Salt of weak diprotic acid and strong base:

In aqueous solution, the salt of a strong base and a weak diprotic acid dissociates completely. The cation from the strong base remains as such and some of the anions from the weak acid react with hydrogen ions in the solution to give monoprotic and diprotic acid depending upon the Ka values of the acids.
