Question

A student is performing an experiment to study the properties of acetic acid. Answer the following questions:
(i) Name the substance he must add to acetic acid to produce carbon dioxide.
(ii) Give the relevant chemical equation for the reaction.
(iii) How would he test CO2 gas in the laboratory?

Answer 1

Answer:

co2

Explanation:

because co2 gas in the laboratory

Answer 2

Test for acetic acid

Explanation:

If your pour acetic acid (CH3COOH) over sodium carbonate (Na2CO3) crystals, there is an immediate fizzing as carbon dioxide (CO2) is produced. The reaction will result in a colourless solution of sodium ethanoate. The CO2 produced will be visible by the effervescence seen caused by the escape of the gas. We can prove that the gas produced is carbon dioxide by passing the gas through lime water. The lime water will turn milky.

Na2CO3 + CH3COOH ---> CH3COONa + CO2 + H2O
