What is the pH of a solution of hydrochloric acid (HCl) at a concentration of 0.

What is the pH of a solution of hydrochloric acid (HCl) at a concentration of 0.01 M?

What is the pH of a solution of hydrochloric acid (HCl) at a concentration of 0.01 M?

Step 1: Understand that pH is a measure of how acidic or basic a solution is.
Step 2: Know that hydrochloric acid (HCl) is a strong acid, which means it completely dissociates in water.
Step 3: Calculate the concentration of hydrogen ions (H+) in the solution. For a 0.01 M HCl solution, the concentration of H+ is also 0.01 M.
Step 4: Use the formula for pH, which is pH = -log[H+].
Step 5: Substitute the concentration of H+ into the formula: pH = -log(0.01).
Step 6: Calculate the logarithm: log(0.01) = -2.
Step 7: Therefore, pH = -(-2) = 2.
