Chemistry (pH and pOH) #3

Chemistry Level 1

Using \(\log 2 = 0.3\), \(\log 10 = 1\) and \(\log 3 = 0.45\), classify the 3 solutions below in A ( pH < 7), B ( pH > 7) or C (pH = 7).

Solution I: \([OH^{-}] = 2 \times 10^{-3}\)

Solution II: \([OH^{-}] = 8 \times 10^{-9}\)

Solution III: \([H^{+}] = 10^{-7}\)
