Question

What is the pH of a .073 M `HCl` solution?

Answer 1

The solution has a pH of 1.14

Explanation:

Since HCl is a strong acid, meaning that it completely ionizes when dissolved in water, the pH can be obtained directly from the concentration using the formula below:

Take the -logarithm of the concentration of hydronium ions that are in the solution:

`pH = -log (0.073M) = 1.14`
