Strong acid
Strong acids dissociate fully in water to produce the maximum number of H + ions. This means if you had one mole of hydrochloric acid (HCl) molecules, they would all 'split' to form one mole of H + ions and one mole of Cl – ions.
Example : Sulphuric acid
Weak acid
Weak acids, such as ethanoic acid (CH 3COOH), do not fully dissociate.
Example : Acitic acid
