Dissociation of
strong and weak acid
A strong acid HA (left) is completely
ionized in water. A weak acid HB (right) exists mostly as
undissociated HB molecules in water. Note that the water molecules
are not shown in this figure.
Examples:
HCl(aq) is completely
ionized.
Ethanoic acid (CH3COOH)
exists in water mostly as undissociated molecules.
Only a small percentage of the molecules are ionized.
