What formula would I use if I was given [OH-] and wanted to find POH?*

1 point
pH = -log[H+]
[H+]= 10^-pH
pOH = -log [OH-]
O [OH-] = 10^-POH

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.
