An ionic (salt) compound reacts with liquid water (i.e., hydrolysis) in a dissociation reaction that forms an aqueous solution of the constituent cations and anions. I'll tell you the Acid or Base list below. Second, the positive charge on the \(Al^{3+}\) ion attracts electron density from the oxygen atoms of the water molecules, which decreases the electron density in the \(\ce{OH}\) bonds, as shown in part (b) in Figure \(\PageIndex{1}\). 1 Response In water, a solution of ammonium perchlorate would be slightly acidic.

Therefore, neither ion will affect the acidity of the solution so, $KCl$ is a neutral salt. The \(Cr^{3+}\) ion is a relatively highly charged metal cation that should behave similarly to the \(Al^{3+}\) ion and form the \([Cr(H2O)_6]^{3+}\) complex, which will behave as a weak acid: \[ Cr(H_2O)_6]^{3+}_{(aq)} \ce{ <=>>} Cr(H_2O)_5(OH)]^{2+}_{(aq)} + H^+_{(aq)} \nonumber\] (K, The \(Br^\) anion is a very weak base (it is the conjugate base of the strong acid \(HBr\)), so it does not affect the \(pH\) of the solution (K, The \(Na^+\) ion, like the \(K^+\), is a very weak acid (K, In contrast, \(SO_4^{2}\) is the conjugate base of \(HSO_4^\), which is a weak acid.
