\(HCO_3^{-}(ag) + HS(ag) \rightleftharpoons CO_3^{2-}(ag) + H_2S(aq)\)

Let \(\displaystyle{H}{C}{O}^{{-}}_{\left\lbrace{3}\right\rbrace}\) be a \(Br\emptyset\) nsted-Lowry acid and let \(HS^{-}\) be a \(Br\emptyset\) nsted-Lowry base. The conjugate base of the acid is then determined by removing an H atom and

a unit of positive charge. The conjugate acid of the base is then determined by adding an H atom anda unit of positive charge.
