hydrolysis of salts and ph

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..

pH of the hydrolysed salt solution [H + ] = ch Now, pH = -log [H + ] Now, -log K w = pK w - log K b = pK..

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..

Basic salts are stronger in their basic nature and show a pH greater than ..

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..

On refluxing with strong aqueous acid or sodium hydroxide solution, nitriles are hydrolyzed to carboxylic acids. The intermediate in both the reactions is the primary amide. ..
