Acids- the Arrhenius definition. Arrhenius acid- substance that dissociates in water to yield hydrogen ions (protons- H ). Acids Dissociate in Solution . Dissociate- acids and bases break apart into ions when placed in water.Example: CaCl2 ?Ca2 2Cl?. . HCl H2O ?H2O H Cl? (Eqn. I)HCl

Arrhenius acid- substance that dissociates in water to yield hydrogen ions (protons- H+)
3. Acids Dissociate in Solution Dissociate- acids and bases break apart into ions when placed in water.
Example: CaCl2 ?Ca2+ + 2Cl
4. HCl + H2O ?H2O + H+ + Cl (Eqn. I) HCl + H2O ?H3O+ + Cl (Eqn. II) Eqn I and Eqn II mean the same thing
