What is the pH of an aqueous hydrochloric acid solution where [H₃O⁺] = 1.0 × 10⁻³ M? Enter numeric value.
Direct Answer: Calculating pH from Hydronium Concentration is defined by: 3. pH = -log₁₀[H⁺] = -log₁₀(1.0 × 10⁻³) = 3.0.
Detailed Step-by-Step Explanation:
pH = -log₁₀[H⁺] = -log₁₀(1.0 × 10⁻³) = 3.0.
