What is the pH of 1 molar HCl solution? (assume complete dissociation)

Options

A1
B2
CZero
D7

Correct answer

C. Zero

Step-by-step solution

HCl is a strong acid and dissociates completely in water. HCl H^+ + Cl^- For a 1 M solution of HCl, the concentration of hydrogen ions is: [H^+] = 1 M pH = - ₁₀[H^+] pH = - ₁₀(1) = 0 Answer: Zero
