Question

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

• A. \( 1 \)
• B. \( 2 \)
• C. \( 3 \)
• D. \( 4 \)

Hint:

For strong acids, the pH is calculated directly from the concentration of the acid since they dissociate completely. Use the formula \( \text{pH} = -\log [\text{H}^+] \).
