salts hydrolysis

Hydrolysis of Salts - Dissolution of different salts in water does not always result in neutral solutions. For example, aqueous solution of copper sulphate is acidic whereas aqueous solution of sodium acetate is basic and aqueous solution of sodium chloride forms neutr..

Dissolution of different salts in water does not always result in neutral solutions. For example, aqueous solution of copper sulphate is acidic whereas aqueous solution of sodium acetate is basic and aqueous solution of sodium chloride forms neutral solution. This is due to the diss..

>The hydrolysis constant 'K h ', of the salt is inversely proportional to the dissociation constant, 'K a ' of the weak acid. Therefore, the weaker the acid, the greater is the hydrolysis constant of the salt..

Water can hydrolyse salts of weak acids with strong bases and of weak bases with strong acids. For example, Hydrolysis of Na 2 CO 3 : The resulting solution is acidic due to the presence of H + ions. Some cases where basic salt are for..

If the original concentration of the salt in the solution is 'c' mol/litre and 'h' is the degree of hydrolysis at that concentration, then Initial Concentration c c 0 0 Concentration at eqilibrium c(1-h) c(1-h) ch ch K h = h 2 o..

If the original concentration of the salt in the solution is 'c' mol/litre and 'h' is the degree of hydrolysis at that concentration, then Intial concentration c 0 0 Concentration at eqilibrium c(1-h) ch ch If 'h' is very small as compared to 1, we..

Primary aliphatic nitro compounds can be converted to aldehydes by treatment of their carbanion salts with sulphuric acid. ..

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..

Salt of Strong Acid and Strong Base - Here, neither the cation nor the anion undergoes hydrolysis. Therefore, the resulting solution is neutral. For example, aqueous solution of KCl is neutral because when dissolved in water, its ions K + and Cl - have no tendency to react with ..
