Solution
To calculate the pH of a 0.000375 M HCl solution, you need to use the formula for pH which is pH = -log[H+].
HCl is a strong acid, which means it completely ionizes in water. Therefore, the concentration of H+ ions is equal to the concentration of HCl.
Step 1: Identify the concentration of H+ ions. In this case, [H+] = 0.000375 M.
Step 2: Substitute the value into the pH formula. So, pH = -log(0.000375).
Step 3: Calculate the pH. Using a calculator, you will find that pH = 3.43.
So, the pH of the 0.000375 M HCl solution is 3.43.
