The percentage degree of hydrolysis of a salt of weak acid (HA) and weak base (BOH) in its 0.1 M solution is found to be `10%.` If the molarity of the solution is 0.05 M, the percentage hydrolysis of the salt should be :

Options

A. KCl undrgoes hydrolysis
B. `K_(h)=K_(b)(A^(-))` and `K_(h)=K_(a)(B^(+))`
C. 0.1 M solution of NACN is acidic
D. resultant solution of equal volume of 0.1 M `NH_(3)` and 0.1M HCl is basic
