Answer:
pOH = -log[OH-]
Step-by-step explanation:
Hello,
To calculate the pH or pOH of a substance, we relate it the negative logarithm of either the H+ or OH- concentration.
pOH is used to find the alkalinity of a solution my measuring the concentration of the hydroxide ion [OH-]. Solutions having a pOH value that is greater than 7 are said to be acidic while solutions with value less than 7 are alkaline.
pH = -log[H+]
While
pOH = -log[OH-]
Note: the pOH value of a solution depends on the concentration of the hydroxide ion in the solution.
