melamori03 [73]
According to Arrhenius theory of acid and base, Acids are those substances which when dissolved in water produces protons, while, Bases are those substances which when dissolved in water produces Hydroxyl Ions.

Example of Arrhenius Bases:

                         
NaOH ₍s₎ → Na⁺ ₍aq₎  +  ⁻OH ₍aq₎

                         LiOH ₍s₎ → Li⁺ ₍aq₎  +   ⁻OH ₍aq₎
Result:
           The only negative ion produced in water when Arrhenius Base is dissolved is ⁻OH (Hydroxyl Ion).
