(a) - Products: ${NO_3}^- and$ $H_3O^+$ Acid: $HNO_3$; Conjugate base: ${NO_3}^-$; Base: $H_2O$; Conjugate acid: $H_3O^+$; (b) - Products: ${SO_4}^{2-}$ and $H_3O^+$ Acid: $H{SO_4}^{-}$; Conjugate base: ${SO_4}^{2-}$ Base: $H_2O$; Conjugate acid: $H_3O^+$ (c) - Products: $H_2O$ and $HF$. Acid: $H_3O^+$; Conjugate base: $H_2O$ Base: $F^-$; Conjugate acid: $HF$
1. Identify the acid and the base. - The acid is the reactant that can donate one of its protons ($H^+$), and the base is the reactant that can receive this proton. 2. Remove one proton from the acid. - Remove 1 hydrogen, and subtract 1 from the charge. - It is one of the products, the conjugate base. 3. Add one proton to the base. - Add 1 hydrogen, and sum 1 to the charge. - It is the other product, the conjugate acid.
