Limewater test for carbon dioxide
Videonummer 11924209
| Limewater test for carbon dioxide. Hydrochloric acid is poured onto chips of calcium carbonate in a test tube. The vigorous reaction between them produces carbon dioxide gas (and calcium chloride and water, neither seen), which passes up the tube and into a beaker of clear limewater. The presence of the carbon dioxide causes the limewater (calcium hydroxide) to turn milky, due to the formation of a precipitate of calcium carbonate. | |
