Is an aqueous solution of \(\mathrm{NaHSO}_{4}\) acidic, basic, or neutral? What reaction occurs with water? Calculate the \(\mathrm{pH}\) of a \(0.10 \mathrm{M}\) solution of \(\mathrm{NaHSO}_{4}\). If solid \(\mathrm{Na}_{2} \mathrm{CO}_{3}\) is added to a solution of \(\mathrm{NaHSO}_{4}\), what reaction occurs between the \(\mathrm{CO}_{3}{ }^{-}\)and \(\mathrm{HSO}_{4}{ }^{-}\)ions?
