The goal of this article is to measure hydrogen produced during the corrosion of magnesium in HCl and the influence of the Triton X‐100 surfactant on hydrogen production. It was found that the hydrogen produced during corrosion of Mg in HCl increased with increasing HCl concentration, stirring rate, temperature, and time of immersion. The addition of the Triton X‐100 surfactant inhibits the amount of hydrogen evolved. The inhibition behavior was explained on the basis of adsorption of Triton X‐100 molecules on the Mg surface creating a barrier for mass and charge transport, which protects the Mg surface from aggressive ions. The activation thermodynamic parameter values were calculated and explicated. Some theoretical chemical parameters were also calculated. The results obtained from the theoretical calculations are in agreement with the practical results.
