2.10 x 10^-10 M. Ans
pH + pOH = 14
Where, pOH is the power of hydroxide ion concentration and pH is the power of concetration of the H + ion.
Now, pOH = 14 - 4.32
Now, the concentration of [H+] is 10-7 M, then pH is 7 and for [OH-] = 10-7 M, the pOH is also 7.
Now, pOH = - log[OH-]
[OH-] = 10^ - pOH
= 2.10 x 10^-10 M
