HSC Chemistry – Acidic Environment R Slider. * The pH of a salt depends upon the relative strength of the ions that make up the salt * Very few salts.

Salts and pH. Soluble salts dissociate in water to produce ions. Salts are basically ionic compounds that can be formed from the reaction from an acid.

Formulas of Acids and Bases Ammonium (NH4+) and acetate (C2H3O2-) are water-soluble ions (no exceptions), but are NOT spectators because they react with water. Ammonium is a weak acid. Acetate is a weak base. Cations are weak acids except H+ (strong acid) and spectators (not acidic). Anions are weak bases except OH- (strong base) and spectators (not basic). Always break formulas into left and right halves and analyze acid/base character of each half. Example: HC2H3O2 is combination of strong acid (H+) and weak base (C2H3O2-); combination results in overall weak acid.
