What is the H+ concentration (in molarity) of a solution with a pOH of 6.7?
You want to use the following relationship:
Since we are given the pOH, we can determine the pH by subtracting the pOH from 14 like so:
14 - pOH = 7.3.
7.3 represents the pH of the solution and we can obtain the concentration of hydrogen ions in solution by taking the antilog of the pH. The antilog is
pH = -log
I hope this explanation is understandable!
