Answer 1

1) Lime (calcium oxide) is a white solid with strongly basic properties. ... 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.

2) Take about 10 mL vinegar in a test-tube and add a pinch of baking soda to it. We will hear a hissing sound and see the bubbles of carbon dioxide gas coming out and rising in the test-tube. Baking soda is sodium hydrogen carbonate and vinegar contains acetic acid.
