Answer:
<u></u>
Explanation:
Lower pH means that the solution is more acidic
<em>A decrease of two units </em>means that the new solution is <em>100 times more acidic </em>than the original one:
The final equality means that the when the <em>pH decreases two units</em>, the new solution is <em>100 times more acidic</em>.
Use the same when the pH decreases from 7.0 to 4.0, which is three units of decrease:
That means that<em> the acid precipiation (pH = 4.0) is 1,000 times more acidic than pure water (pH = 7.0)</em>
