Calculate the concentration of hydroxide ions (OH-) in a solution with a pOH of 2.52?

The concentration of hydroxide ions is 3.02*10⁻³ M

Explanation:

The pOH (or OH potential) is a measure of the basicity or alkalinity of a contamination and is defined as the negative logarithm of the activity of the hydroxide ions. That is, the concentration of OH - ions:

pOH = - log [OH-]

The pOH has a value between 0 and 14 in aqueous solution, the solutions with pOH being greater than 7 being acidic, and those with pOH less than 7 being basic.

If pOH = 2.52 then

2.52 = - log [OH-]

[OH-] = 3.02*10⁻³ M

The concentration of hydroxide ions is 3.02*10⁻³ M
