This indicates that the [OH−] of the solution

has

1. increased by a factor of 100.

2. increased by a factor of 2.

3. decreased by a factor of 2.

4. decreased by 2 M.

5. decreased by a factor of 100.

**DrBob222**, Sunday, June 8, 2014 at 2:57pm5 is the answer.

5.5 to 3.5 the solution has become more acid by pH of 2 and since this is a log term (pH = -log(H^+) that's more acidic by a factor of 100.

So OH must have decreased by a factor of 100.
