Strong Acids/Weak Acids

How strong an acid is depends on how much it dissociates.

Strong acid- HCl, H2SO4, HNO3

HCl + H2O ----> Cl– + H3O+

Keq= infinity (big)

Weak acid- acetic acid CH3COOH

CH3COOH + H2O ----> CH3COO– + H3O+

Keq= 1.82 X 10-5 (small)

The Keq is a constant which you would be given
