Acid + Carbonate
Acids react with metal carbonates produces salt, water and carbon dioxide
Example of Experiment
- About 5 cm³ of dilute sulphuric acid is poured into a test tube.
- One spatula of calcium carbonate powder is added into the test tube.
- The gas released is passed through lime water as shown in the diagram above.
- The observations are recorded
Colourless gas is released. The gas turn lime water chalky.
Sulphuric acid reacts with calcium carbonate.
The gas released is carbon dioxide.
H2SO4 +CaCO3 → CaSO4 +CO2 + H2O
