Answer:
The concentration of hydroxide ions is 3.02*10⁻³ M
Step-by-step 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
