When NaHSO4 is in water, it ionizes to Na^+ , H+, and SO4^-2. Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). The pH of the six salt solutions varied across a wide range of pH values. When will acid-base reactions occur before substitution reaction. If Ka(cation) = Kb(anion) the solution of the salt isneutral. i don't , it seem be an acid NaH2PO4, Sodium dihydrogen phosphate, is an acid. As an example, $\pu{0.1 M}$ solution of such a salt will have a pH of about $4.7$. N a X 2 H P O X 4 is amphoteric, which means it can act as a base or as a acid depending on which substance they react with.
