Matthew Hicks · Answer 1

The pH of the solution is 3.00.

Explanation:

The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:

pH = - log (H30 + )

pH = - log (1x10^-3)

pH = 4.00
