Question

Find out h+ concentration of 1m hcn solution if its degree of dissociation is 4.0*10^-10

Answer 1

Answer:

Explanation:

here , given solution HCN;

and Ksp = 4 * 10^-10

so HCN = H+ + CN^-

Ksp = [H+]*[CN-] = 4*10^-10 but we now that [H+] = [CN-]

so, [H+]^2 = 4* 10^-10

[H+] = 2* 10^-5 M
