Answer:
First To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.
The given $pOH $ of solution is 8.99. To find its pH value we will use the formula, $pOH=14-pH$. So, pH = 14-8.99 = 5.01.
