Acetic acid (CH 3 COOH) is a weak acid because it partially dissociates in an aqueous solution or it does not ionize completely in solution to produce H + ions. In acetic acid, CH 3 COOH, the electron releasing -CH 3 group increases the negative charge on the carboxyl group, making loss of proton more difficult. Between ClCH2COOH and CH3COOH, which one is more acidic, and why Why is HF a weak acid and HCl a strong acid?
