Question

How many times more acidic is solution A with a pH of 3.4 than solution B with a pH of 8.4?
Solution A is _________ times more acidic than solution B.
(Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to the nearest tenth as needed.)

Answer 1

Answer:

Solution A is 1 x 10⁵ times more acidic than solution B

Explanation:

The pH scale is a logarithmic scale used to express the acidity or basicity of a solution.

The values are written from 1 - 14 with 1 being the most acidic and 14 a basic solution.

Each interval is ten folds more concentrated than the next because it is a logarithmic scale.

 Since the pH of A = 3.4

                  pH of B  = 8.4

 The difference  = 8.4  - 3.4  = 5.0

So, Solution A is 1 x 10⁵ times more acidic than solution B
