  1. What Gas Is Produce When A Dilute Acid Reacts With The Carbonate For A Metal? It is carbon dioxide, CO2, evolving from acid reaction with Metal carbonate:

    MeCO3(s, aq) + H3O+aq --> Me2+aq + CO2,gas + H2Ol

  2. How do you test for this gas?Let the gas bubble through saturated calcium hydroxide solution, then a precipitate of CaCO3 calcium carbonate will form:

    Ca2+aq + CO2,gas + 2 OH-aq --> CaCO3,s + H2Ol

Hydrogen. Typically, when a metal reacts with an acid, hydrogen is displaced, the metal binds with the anion portion of the acid to form a salt, and molecular hydrogen is formed from the displaced hydrogen, evolving from the solution.

The traditional test is to allow some of the gas to bubble up through some limewater. If the limewater turns milky white then the gas is CO2.
