What is the concentration of hydronium ions in a 0.01m solution of hcl?

0.01 M

Explanation:

1) Dissociation:

Since HCl is a strong acid, it dissociates 100% in water to form hydronium (H₃O⁺) and chloride (Cl⁻) ions, as per this chemical equation:

HCl + H₂O → H₃O⁺ + Cl⁻

2) Concentrations:

Hence, each mole of HCl molecules yields 1 mol of hydronium (H₃O⁺) and 1 mol of chloride (Cl⁻) ions.

Thus, [HCl] = [H₃O⁺] = [Cl⁻] = 0.01 M

3) Conclusion: the concentraion of hydronium ions in a 0.01 M solution of HCl is 0.01 M
