VII. Other properties. A. A mineral exhibits effervescence if it reacts to weak acid by generating bubbles of gas. Calcite, CaCO 3, gives off carbon dioxide gas, CO 2, when it is exposed to a tiny drop of acid.These bubbles are visible at the top of the specimen shown below. B. Dolomite, CaMg (CO 3) 2, will effervesce if powdered on the streak plate before acid is applied.
