What is the ph of a solution that has a [h ] = 0. 0039 m?
Sedbober [7]

The pH of a solution that has a H⁺ ion concentration is 0.0039M is 2.4.

<h3>What is pH?</h3>

pH of any solution gives idea about the acidity or basicity of solution and it will be calculated as:

pH = -log[H⁺]

Given that, concentration of H⁺ ion = 0.0039 M

On putting tis value in pH equation, we get

pH = -log(0.0039)

pH = -(-2.4) = 2.4

Hence required value of pH is 2.4.
