Concept Introduction:
pOH definition:
The pOH of a solution is defined as the negative base-10 logarithm of the hydroxide ion
Relationship between pH and pOH:
pOH is similar to pH. The only difference is that in pOH the concentration of hydroxide ion is used as a scale while in pH, the concentration of hydronium ion is used.
The relationship between the hydronium ion concentration and the hydroxide ion concentration is given by the equation,
As pOH and pH are opposite scale, the total of both has to be equal to 14
