Explanation:
Let us assume that the concentration of [
and
is equal to x. Then expression for
for the given reaction is as follows.
![K_{w} = [OH^{-}][H^{+}]](https://tex.z-dn.net/?f=K_%7Bw%7D%20%3D%20%5BOH%5E%7B-%7D%5D%5BH%5E%7B%2B%7D%5D)


Now, we will take square root on both the sides as follows.
M
Thus, we can conclude that the
concentration in neutral water at this temperature is
M.
