Calculate pOH:
The relationship between pH and pOH is given by:
pH + pOH = 14
So, pOH = 14 - pH
pOH = 14 - 3.5
pOH = 10.5.
Calculate [OH-]:
The hydroxide ion concentration is related to pOH by the formula:
[OH-] = 10^(-pOH)
[OH-] = 10^(-10.5)
[OH-] = 3.16 x 10^(-11) M.
Therefore, the hydroxide ion concentration for a solution with pH = 3.5 is 3.16 x 10^(-11) M.
