Calculate pH for 7.4x10-3 M HCl acid solutionGroup of answer choices212.133

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, the concentration of HCl is given as 7.4x10^-3 M.

So,

pH = -log(7.4x10^-3)

Using a calculator to compute the log,

pH = 2.13

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