Calcium carbonate give out carbon dioxide. to test this statement we have to pass carbon dioxide through lime.
When we do this, we will get to know that lime water will slowly turn milky. This proves the existence of CO2 in Lime
Equation for this test is:
Ca(OH)2+CO2=CaCO3+H2O

Answer:
Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3. Adding more carbon dioxide results in the precipitate dissolving to form a colourless solution of calcium hydrogencarbonate.
