Answer:
A solution with a ph of 6 has 100 times as many hydrogen ions as a solution with a ph of 8.
Step-by-step explanation:
At 7 on the pH scale, a solution is neutral. Any pH lower than 7 is acidic and any pH above 7 is basic.
Acidity is a measure of the concentration of hydrogen ions in a solution. The more acidic a solution, the more hydrogen ions it has. Therefore, if the pH is decreasing, the hydrogen ion concentration is increasing.
The pH scale increases by a factor of 10. This means that for every one unit change, the hydrogen ion concentration changes tenfold. Therefore, if the pH is decreasing by 2 units (from pH 8 to pH 6), the hydrogen ion concentration should increase 100-fold (10 x 10 = 100).
