Solution G has 100 times more hydroxide ions than Solution F.

Explanation:

∵ pH + pOH = 14.

∴ pOH = 14 - pH.

For solution F:

pOH = 14 - pH = 14 - 11 = 3.

∵ pOH = - log[OH⁻] = 3.

∴ [OH⁻] = 0.001 M.

For solution G:

pOH = 14 - pH = 14 - 13 = 1.

∵ pOH = - log[OH⁻] = 1.

∴ [OH⁻] = 0.1 M.

∴ [OH⁻] of solution G / [OH⁻] of solution F = (0.1) / (0.001) = 100.

So, Solution G has 100 times more hydroxide ions than Solution F.
