Answer : The correct option is, 10^{-4}M

Explanation : Given,

pH = 10

First we have to calculate the pOH.

pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-10=4

Now we have to calculate the OH^- concentration.

pOH=-\log [OH^-]

4=-\log [OH^-]

[OH^-]=1.0\times 10^{-4}M

Therefore, the OH^- concentration is, 1.0\times 10^{-4}M
