Question

A chemist is using a solution of hno3 that has a ph of 3.75. what is [h ] for the solution?

Answer 1

A chemist is using a solution of HNO₃ that has a pH of 3.75. what is [H⁺] for the solution is 1.7 × 10⁻⁴M.

How do we calculate the [H⁺]?

Concentration of H⁺ ion will be calculated by using the below equation of pH as:

pH = -log[H⁺]

or [H⁺] = $10^{-pH}$

Given that, pH = 3.75

So concentration of H⁺ ion will be calculated as:

[H⁺] = $10^{-3.75}$

[H⁺] = 1.7 × 10⁻⁴M

Hence concentration of H⁺ ion is 1.7 × 10⁻⁴M.
