Question

The concentration of hydrogen in soil sample 13 * 10 ^ - 6 * M the soil is tested with a pH meter, what value should the meter read?

Answer 1

pH = 4.9

Step-by-step explanation:

Given data

[H⁺] = 13 × 10⁻⁶ M

The pH is a scale used to determine the acidity or basicity of a solution. The pH is related to the concentration of hydrogen ions through the following expression.

pH = -log [H⁺]

pH = -log 13 × 10⁻⁶

pH = 4.9

Since the pH < 7, the soil is considered to be acid.
