The pOH of a solution of KOH is 11.30. What is the [H*] for this solution?​
Sloan [31]

Answer: The concentration of hydrogen ions for this solution is 1.99 \times 10^{-3}.

Explanation:

Given: pOH = 11.30

The relation between pH and pOH is as follows.

pH + pOH = 14

pH + 11.30 = 14

pH = 14 - 11.30

= 2.7

Also, pH is the negative logarithm of concentration of hydrogen ions.

pH = - log [H^{+}]

Substitute the values into above formula as follows.

pH = -log [H^{+}]\\2.7 = -log [H^{+}]\\conc. of H^{+} = 1.99 \times 10^{-3}

Thus, we can conclude that the concentration of hydrogen ions for this solution is 1.99 \times 10^{-3}.
