the relationship between a weak electrolyte and a weak acid or base

Substances, which give poorly conducting solutions when dissolved in water because they are ionized to a very small extent are called as weak electrolytes. For example, NH 3 , CH 3 COOH, H 2 CO 3 , organic bases etc...

A weak electrolyte is one which undergoes partial ionization or dissociation. Here, in solution the ions and the dissociated molecules will be in equilibrium with each other. When such a solution is diluted, the degree of ionization increases. It becomes complete at infinite di..

This type of titration is carried out between a weak acid such as acetic acid (CH 3 COOH) and weak base such as ammonium hydroxide (NH 4 OH). There is no sharp change in the pH during the titration. Hence, no sharp equivalence point can be obtain..

Salt of Weak Acid and a Weak Base - In this case both the cation and anion undergo hydrolysis to the same or different extents. The resulting solution may be neutral, acidic or basic depending upon the relative strengths of acids and ..

An acid which dissociates very feebly in water and whose molecules mostly remain in the undissociated form is categorized as a weak acid. It behaves as a weak electrolyte. ..

A base that dissociates only partially into ions in aqueous medium is called a weak base. It behaves as a weak electrolyte..

Here, cation B + undergoes hydrolysis to give free H + ions. Therefore the resulting solution will be acidic in character having pH less than 7. For example, ..

Here, the anion (A - ) is a stronger base than OH - , hence it undergoes hydrolysis to give free OH - ions. Therefore the resulting solution will be basic in character having pH greater than 7. For example Other examples of this type of salts are CH 3 COONa, Na 2 CO 3 , Na 3 PO 4 , et..

Salt of a Strong Acid and Weak Base - Here, cation B + undergoes hydrolysis to give free H + ions. Therefore the resulting solution will be acidic in character having pH less than 7. For example, Other examples of this type of salts are NH 4 Cl, CuSO 4 , AlCl..

Electrolytes and Non-electrolytes - An ionic or electrovalent compound that conducts electricity in molten (fused) or aqueous (solution) state can be classified as an electrolyte. However, if the compound is unable to ionise it does not conduct electricity it is called..
