Question

name the gas evolved when ethanoic acid react with sodium carbonate. how would you identify this gas?

Answer 1

The gas evolved is Carbon dioxide. We will identify it by passing it by lime water.. It will turn milky so its carbon dioxide.

Answer 2

When ethanoic acid is added to sodium carbonate, a gas called carbon dioxide($CO_{2}$) is produced.

Ethanoic acid is added to sodium carbonate:

• When ethanoic acid is added to sodium carbonate, the reaction is as follows:
• $2CH_{3} COOH + Na_{2} CO_{3}$ → $2CH_{3} COONa + H_{2} O + CO_{2}$
• Carbon dioxide ($CO_{2}$) gas is evolved in the reaction.

Identification of the gas evolved:

• Carbon dioxide combines with calcium hydroxide solution to form a white calcium carbonate precipitate.
• Limewater is a calcium hydroxide solution.
• Limewater turns milky or hazy white when carbon dioxide is bubbled through it.
• Carbon dioxide is colorless and odorless, and you're exhaling it right now.
• It's also what gives your soda its fizz.
