Problem

Four separate beakers contain the following solutions at

25\,^{\circ}\text{C}

: I.

pH = 3.00

II.

[\text{OH}^-] = 1.0 \times 10^{-4}\,\text{M}

III.

0.010\,\text{M HCl}(\text{aq})

IV.

pOH = 2.00

Which of the following correctly ranks the solutions from most acidic to most basic? a)

\text{I} < \text{III} < \text{II} < \text{IV}

\text{III} < \text{I} < \text{II} < \text{IV}

\text{IV} < \text{III} < \text{I} < \text{II}

\text{III} < \text{I} < \text{IV} < \text{II}
