Hydrolysis of salts and pH of their solutions

Hydrolysis of calcium carbid gives a solution with Ph

Derive an expression for (i)degree of hydrolysis ,(ii) hydrolysis constant and pH of salt of weak acid and weak base.

HA is a weak acid and BOH is a weak base. For which of the following salts the extent of hydrolysis is independent of the salt in its aqueous solution

When a salt reacts with water resulting into formation of acidic or basic solution, the process is referred to as salt hydrolysis. The pH of salt solution can be calculated using the following equations. pH = ( 1)/(2) ( p K_(w) + pK_(a) + log C) for salt of weak acid and strong base. pH = (1)/(2) ( pK_(w)- pK_(b) - log C ) for salt of weak base and strong acid. pH = (1)/(2) ( pK_(w) + pK_(a) - pK_(b)) for salt of weak acid and weak base The pH of 1M PO_(4(aq))^(3-) soluiton will be ( given pK_(b) of PO_(4)^(3-) = 1.62 )

The degree of hydrolysis of which of the following salt is independent of the following salt is independent of the concentration of salt solution?
