Assertion`:-` Degree of hydrolysis and pH of a `WAWB` salt is independent of initial concentration of salt.
Reason`:-` The solution of `NH_(4)CN` in water has pH slightly greater than ?

Assertion : Degree of hydrolysis and pH of a salt, e.g. NH_(4)CN is independent of concentration of NH_(4)CN Reason : The solution of NH_(4)CN in water has pH slightly greater than 7 .

The pH of which salt is independent of its concentration ?

Give an example of a salt solution whose pH is independent of salt concentration.

Show that the degree of hydrolysis of a salt of weak acid and weak base is independent of concentration of the salt.

Explain the following: (a)pH of 10^(-7) M HCl is not 7. (b)Degree of hydrolysis of an aqueous solution of a salt of weak acid and weak base is independent of initial concentration of the salt. (c) The aqueous solution of NH_4Cl is acidic. (d)A mixture of sodium acetate and acetic acid resis changes in pH value on adding acid or base .
