An acid with a H+ molarity of 1x10^-3 M has a PH of?

The answer to your question is pH = 3

Explanation:

Data

[H⁺] = 1 x 10⁻³

pH = ?

pH is a measure of the hydrogen concentration. It measures the acidity or alkalinity. The range of pH goes from 0 to 14. The pH for an acid is from 0 to 6.9, for a neutral solution is 7.0 and for an alkali is from 7.1 to 14.

Formula

             pH = -log [H⁺]

-Substitution

             pH = -log [1 x 10⁻³]

-Simplification

             pH = - (-3)

-Result

             pH = 3

a is the correct answer
