# 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: $$[H^{+}] = 10^{-7}$$
