Question

Scenario: You are testing two different household solutions with your cabbage indicator, using the color key to the right.

Using the results from the two previous questions:

Solution One: 1 x 10es001-1.jpg M

Solution Two: 1 x 10es001-2.jpg M

The hydrogen ion concentration of these two solutions differ from each other by a factor of
.

Answer 1

I can’t see the images, so I don’t know the pH values you read from your cabbage indicator. Tell me either the two pH values (from the color key) or describe the two indicator colors and the key mapping, and I’ll compute the factor.

How to compute it:
- If pH1 and pH2 are the pH values of Solution One and Solution Two, the ratio of their hydrogen‑ion concentrations is [H+]1/[H+]2 = 10^(pH2 − pH1).
- The factor by which they differ (always >1) is 10^(|pH1 − pH2|).

Example: if Solution One is pH 3 and Solution Two is pH 6, the H+ concentration differs by 10^(6−3) = 10^3 = 1000 (Solution One has 1000 times more H+).
