HX is a weak acid (Ka = 10-5). It forms a salt NaX (0.1M) on reacting with caustic soda. The degree of hydrolysis of NaX is

dear student,

Degree of hydrolysis of salt of weak acid with strong base = sqrt(Kw/(cKa))

Here Kw = 10^-14 Ka = 10^-5 c = 0.1

So dwgree of hydrolysis = sqrt(10^-8) = 10-4

BEST OF LUCK..!!!!
