Answer 2

Answer:

(a) In the test tube where the gas is collected, Saloni needs to add some water. She must cover the tube and shake it vigorously. She’ll now use both red and blue litmus to test the solution. When blue litmus turns red, it indicates that the gas is acidic.

(b) Carbon dioxide gas is formed when charcoal combines with oxygen.

C + O2 → CO2

When carbon dioxide gas combines with water, it produces carbonic acid, an acidic compound that turns blue litmus red.

CO2 + H2O→ H2CO3
