WebpOH or potential of hydroxide ion is a scale used to determine the hydroxide ion (OH –) concentration in a solution. It is a quantitative measure of the acidity or alkalinity of a solution. It equals the negative log of hydrogen ion (OH –) concentration. At pOH 7 solution is found to be neutral. WebAnswer: pOH = 11.6, pH = 2.4. The acidity of a solution is typically assessed experimentally by measurement of its pH.
