Answer: The concentration of hydrogen ions for this solution is
1.99 * 10^(-3).

Step-by-step 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 * 10^(-3)

Thus, we can conclude that the concentration of hydrogen ions for this solution is
1.99 * 10^(-3).
