Answer:
- Calcium hydroxide is sparingly soluble in water producing an alkaline solution known as limewater. When carbon dioxide gas is passed through or over limewater, it turns milky due to the formation of calcium carbonate.
Chemically the ethanoic acid reacts with the sodium hydrogen carbonate to form carbon dioxide gas and water. ... Because carbon dioxide is heavier than air, it cannot escape away from the reaction so it appears to flow down over the edges of your cup cake tin looking a little like lava flowing out of a volcano.
