Experiment What would happen when carbon dioxide reacts with limewater?

Materials a test tube limewater a straw a funnel

Procedures Pour limewater into test tube Blow bubbles into cup for at least one minute (caution— do not drink the solution) Video https://www.youtube.com/watch?v=6HuyUxJBY3E

Results When carbon dioxide reacts with limewater, it turns __________________

Results When carbon dioxide reacts with limewater, it turns white/cloudy/milky.

Independent learning on the VLE Repeat the same experiment at home and compare your results. The products of this reaction are calcium carbonate (the same chemical as chalk - that is why it goes milky!
