Question

A solution with a pH of 6 has a ______ difference in H ion concentration than a solution with pH of 10.

Answer 1

Answer:

9.999x10^-7M

Explanation:

First, let us calculate the concentration of the hydrogen ion in both cases:

For pH 6:

pH = —Log [H+]

6 = —Log [H+]

—6 = Log [H+]

Take the anti-log of —6

[H+] = 1x10^-6M

For pH 10:

pH = —Log [H+]

10 = —Log [H+]

—10 = Log [H+]

Take the anti-log of —10

[H+] = 1x10^-10M

The difference between the [H+] of pH 6 and [H+] of pH 10 is given by:

1x10^-6 — 1x10^-10 = 9.999x10^-7M
