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 +
