Unformatted text preview: O ion) , the Arrhenius definitions of acid and base are still valid today, as long as we are talking about aqueous solutions. In summary, according to Arrhenius: When we dissolve an acid (a molecular When we dissolve a base(an ionic + substance) in water, the molecules of acid substance) in water, the metallic ions, M + react with water to produce H3O ions. and the hydroxide ions, OH separate. H2O H2O + ─ HCl(g) ───────> H3O (aq) + Cl (aq) NaOH(s) ──────¾>Na+ (aq) + OH (aq) Accepted simplification: Accepted simplification: + ─ HCl(aq) ───────> H (aq) + Cl (aq) NaOH(aq) ──────> Na+ (aq) + OH (aq) The aqueous solution of the acid contains ions only (no molecules) The acidic solution is a strong electrolyte (Complete dissociation took place) Acids which are completely dissociated in ions in aqueous solutions are called strong acids 3 The aqueous solution of the base contains ions only (no molecules) The basic solution is a strong electrolyte (Complete...
