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
.
A cabbage p H indicator color key. Entries are 0 to 2, bright red; 3 to 4, pink; 5 to 6, purple; 7, dark violet; 8 to 9, blue; 10 to 11, bright green; 12 to 13, lighter green.

Answer 1

They differ by a factor of 10.

Calculation: (1 × 10⁻¹) / (1 × 10⁻²) = 10 — so Solution One has ten times the [H+] of Solution Two (pH differs by 1).
