What is the pH of a 1×10−41×10−4 mol HCl solution? (1 point) Responses 2 2 6 6 4 4 8

Answer 1

The pH of a solution can be calculated using the formula: pH = -log[H+].

In this case, since the solution is HCl (a strong acid), it will dissociate completely in water to form H+ ions.

Therefore, the concentration of H+ ions in the solution will be equal to the concentration of HCl.

Given that the concentration of HCl is 1x10^-4 mol, the concentration of H+ ions is also 1x10^-4 mol.

Taking the negative logarithm of 1x10^-4 gives us pH = -log(1x10^-4) = 4.

Therefore, the pH of the 1x10^-4 mol HCl solution is 4.
