Question

Calculate the pH of a hydrochloride acid solution, HCl, whose hydronium ion (H3O)+ concentration is 8.29 X 10-4 M.

Note: answer should have three significant figures

Answer 1

The pH of the hydrochloride acid solution with a hydronium ion concentration of 8.29 × 10^-4 M is 3.082, rounded to three significant figures.

Step-by-step explanation:

To calculate the pH of a hydrochloride acid solution (HCl) with a hydronium ion concentration of 8.29 × 10^-4 M, we can use the formula: pH = -log[H3O+] Inserting the given concentration: pH = -log(8.29 × 10^-4) Using a calculator, we find: pH = 3.082 The pH of the hydrochloride acid solution is 3.082, rounded to three significant figures.
