Neglecting the $\ce{OH^-}$ produced by the autoprotolysis of water, it is valid to make the usual assumption that $\ce{[OH^-]}={[HCO_3^-]}$,and little of the carbonate goes to bicarbonate,so$\ce{[CO_3^{-2}]}={[CO_3^{-2}]_0}=0.5$ ,so thus We've added a "Necessary cookies only" option to the cookie consent popup, Combining acid dissociation constants to determine pH of diprotic acid. It presents a large capacity to absorb moisture. Answer : K2CO3 ( POTASSIUM CARBONATE ) is base.
