A weak acid is an acid that does not fully ionize in solution; that is, if the acid was represented by the general formula AH, then in aqueous solution a significant amount of undissolved AH still remains.

HA_(aq) H⁺_(aq) + A^-_(aq) The vast majority of acids are weak acids.

Examples

• Phosphoric acid, H₃PO₄
• Acetic acid, CH₃COOH
• Hydrofluoric acid, HF
• Acetylsalicylic acid, C₆H₄OCOCH₃CO₂H
• Nicotinic acid, C₅H₅NCOOH
• Pyruvic acid, CH₃COCOOH
• Bromothymol blue, C₂₁H₁₅NaBr₂O₃S
