Answer #1

HClO ---------------------> ClO-   + H+

8.4 x10^-3                        0          0           -----------------initial

8.4 x10^-3-x                     x            x         --------------------at equilibrium

Ka= [ClO-][H+]/[HClO]

3x 10^-8 = x^2/(8.4 x10^-3-x )

by solving this we get

x= 1.6 x10^-5

concentration of [ClO-] = 1.6 x10^-5 M
