If you have an unknown phenol, what pH you need to achieve upon re-acidification with HCl to ensure that your phenol is 99.9% back in its neutral form? Assume a pKa of 10 for your phenol, and remember that the pH needs to be 3 units different from the pKa for 99.9% ionization or neutralization. pH 5 or lower pH 7 or lower pH 13 or lower pH 2 or lower
