WebDec 30, 2024 · An acid is a substance that liberates an H + ion or proton when dissolved in water and has a pH value from 1 to 6. So, CH 3 COOH is considered an acid. When it is dissolved in an aqueous solution, it dissociates into two parts (CH 3 COO – and H + ), the presence of H+ ion in the aqueous solution of CH3COOH makes it acid in nature. WebThe cation will be a spectator. Thus the basic salts will be composed of a spectator ion like sodium, Na +, potassium, K + or something like that and an anion that is the conjugate base of the acid. They can be identified as they are the same compound as the weak acid but they are "missing" a H +. Thus F - is the conjugate base of HF.
