WebIn the reaction between acetic acid, CH 3 CO 2 H, and water, H 2 O, water acts as a base. The acetate ion CH 3 CO 2- is the conjugate base of acetic acid, and the hydronium ion H 3 O + is the conjugate acid of the base, water: CH 3 COOH + H 2 O ⇌ CH 3 COO - + H 3 O +. Water can also act as an acid, as when it reacts with ammonia. WebAug 19, 2008 · 1. there are many acids, and each one has its own 'strength'. sulphuric acid is a stronger acid than ethanoic acid. if you have ethanoic acid reaction with NaOH, you will get the salt sodium ethanoate. but if you then add sulphuric acid to this salt, the weaker ethanoic acid will be displaced by the stronger sulphuric acid to give sodium ... resume js
