salts undergo 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..

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..

The hydrolysis constant may be written as: The hydrolysis constant 'K h ', of the salt is inversely proportional to the dissociation constant, 'K b ' of the weak b..

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..

Hydrolysis of Aliphatic Nitro Compounds - Primary aliphatic nitro compounds can be converted to aldehydes by treatment of their carbanion salts with sulphuric acid. Secondary nitro alkanes hydrolyze with boiling HCl to give ketones and nitrous oxid..

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 r..

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 bases. The hydrolysis may be written as: ..

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, ..
