Answer:
[H₂O] > [H₃O⁺] ≳ [Cl⁻] > [OH⁻] > [HCl]
Explanation:
HCl + H₂O ⟶ H₃O⁺ + Cl⁻
HCl dissociates completely in solution.
[HCl] = 0 mol·L⁻¹
[H₃O⁺] = 1.0 × 10⁻⁶ mol·L⁻¹
[Cl⁻] = 1.0 × 10⁻⁶ mol·L⁻¹
[H₃O⁺] is slightly greater than [Cl⁻] because the autoionization of water also creates some hydronium ion.
1 L of water has a mass of 1000 g.
∴ [H₂O] = 55.49 mol·L⁻¹
∴ [H₂O] > [H₃O⁺] ≳ [Cl⁻] > [OH⁻] > [HCl]
