Answer
An Arrhenius acid is a substance which produces $H^+$ ions when dissolved in an aqueous solution.
A Bronsted-Lowery acid is a substance which donates protons in solution.
A Lewis acid is a substance which accepts electron-pairs.
The Lewis acid is the most general.
Work Step by Step
Arrhenius Acid Reaction:
$HCl \Rightarrow H^+ + Cl^-$
Bronsted-Lowry Acid Reaction:
$HCl+H_2O\Rightarrow H_3O^++Cl^-$
Lewis Acid Reaction:
$Ni^{2+}_{(aq)}+6NH_{3(aq)}\Rightarrow Ni(NH_2)_{6(aq)}^{2+}$
