Answer 1

Answer #1

6)
At pH 6:
use:
pH = -log [H+]
6 = -log [H+]
[H+] = 1*10^-6 M

At pH 7:
use:
pH = -log [H+]
7 = -log [H+]
[H+] = 1*10^-7 M

At pH 8:
use:
pH = -log [H+]
8 = -log [H+]
[H+] = 1*10^-8 M

These concentrations differ by a factor of 10

7)
When pH increases, concentration is decreasing.
For each unit increase in pH, concentration decreases by a factor of 10.
