Due to this effect, the acidity of hydrated metal ions increases as the charge on the metal ion increases and its radius decreases. -The ions from $KCl$ derived from a strong acid (HCl) and a strong base (KOH). Methylammonium chloride is acidic because methylammonium ion is an acid and Cl- is not a base. 2. (b) The positive charge on the aluminum ion attracts electron density from the oxygen atoms, which shifts electron density away from the OH bonds. A base is defined as a proton acceptor or lone pair donor.
