Which is the correct alternate for hydrolysis constant of `NH_(4)CN`?

Which is the constant equation for hydrolysis constant of NH_(4)CN ?

Which is the constant equation for hydrolysis constant of NH_(4)CN ?

The correct relation for hydrolysis constant of NH_4CN is :

The dissociation constant of NH_4OH is 1.8xx10^(-5) predict the hydrolysis constant of NH_4Cl

Find the degree of hydrolysis, pH of the solution and hydrolysis constant for a 0.001(M) NH_4Cl solution at 25^(@)C provided K_b[NH_3]=1.8xx10^(-5)

Dissociation constant of NH_(4)OH is 1.8 xx 10^(-5) . The hydrolysis constant of NH_(4)Cl would be
