#### Answer

ph=2, Acidic ph=12, Basic

#### Work Step by Step

The definition of pH is the negative logarithm of the Hydrogen Ion Concentration. A pH less than 7 is acidic. Because the Hydroxide Ion concentration is given instead of the hydrogen ion concentration, we must calculate pOH instead. The definition of pOH is the negative logarithm of the Hydroxide Ion Concentration. Remember the sum of pH and pOH is 14. A pH greater than 7 is basic.
