Acidity. As you go down it’s more of an acid as you go up it becomes more of a base
Explanation:
We know that the relation between pH and concentration of hydrogen ions is as follows.
pH = [tex]-log [H^{+}][/tex]
or, pH = [tex]log \frac{1}{[H^{+}]}[/tex]
As, pH is inversely proportional to the concentration of hydrogen ion. So, a decrease in the pH value will lead to an increase in tenfold (10X) compared to what it was at pH 9.
Thus, we can conclude that if the pH of a solution is decreased from 9 to 8, it means that the concentration of H has increased tenfold (10X) compared to what it was at pH 9.
