Calculate pH for 7.4x10-3 M HCl acid solutionGroup of answer choices2.13132

To calculate the pH of a solution, you can use the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution.

For a strong acid like HCl, it dissociates completely in water, so the concentration of H+ ions is equal to the initial concentration of the acid.

Here are the steps to calculate the pH:

1. Identify the concentration of the HCl solution, which is 7.4x10^-3 M. This is also the [H+] in the solution because HCl is a strong acid and dissociates completely.

2. Substitute the [H+] into the pH formula: pH = -log(7.4x10^-3)

3. Calculate the pH using a calculator. The result is approximately 2.13.

So, the pH of the 7.4x10^-3 M HCl solution is approximately 2.13.
