Which of the following expressions is applicable to the hydrolysis equilibrium? CN^(-) + H_2 OhArrHCN +OH^(-)

Answer»

`K_h = (k_(w))/(K_a)`
`H=( sqrt(k_h)/(C ))`
`pH =1/2 pK_a [HCN]`
`[H^+] = sqrt((k_w XX K_a)/(C ))`

Solution :`K_h = (k_(w))/(K_a)`
`h=( sqrt(k_h)/(C ))`
`[H^+] = sqrt((k_w xx K_a)/(C ))`
