salt + water + carbon dioxide
Method
Using a measuring cylinder, measuring 15 cm° of hydrochloric acid and place into the boiling tube
Using a clean measuring cylinder, measure 5 cm° of limewater and place into a test-tube. Place the test-tube and boiling tube side by side in a test-tube rack.
Carefully add the calcium carbonate to the acid - record your observations
Using the disposable pipette/dropper, collect the gas produced by opening and closing the dropper above the reaction in the boiling tube.
Once the gas has been collected in the disposable oipette/dropper, bubble the gas through the limewater and record your observations.
Observations
fizzes with acid
limewater - colourless to milky makes precipitate
