... An example of a strong electrolyte undergoing ionization is as follows: HCl (aq) + H2O (l) → H3O+ (aq) + Cl- (aq) This reaction may be abbreviated as: HCl (aq) → H+ (aq) + Cl- (aq) 2. The common strong bases are the soluble hydroxides (those of Group IA elements and Ba2+) and the slightly soluble hy ...
