Question

acetic acid was taken in a test tube and sodium metal added through a thistle funnel
1. which gas is evolved in the experiment
2.write one test to identify the gas

Answer 1

hydrogen gas, candle burns with a pop sound
happy new year in advance

Answer 2

Answer:

For 1: The gas evolved is hydrogen gas.

For 2: If we bring the match stick near test tube, the gas will burn with a pop sound.

Explanation:

• For 1:

The reaction of acetic acid having formula $CH_3COOH$ with sodium metal, will lead to the formation of sodium ethanoate with the release of hydrogen gas.

The equation corresponding this reaction follows:

$2CH_3COOH+2Na(s)\rightarrow 2CH_3COONa+H_2(g)$

• For 2:

The release of hydrogen gas can be tested when we bring a burning match stick near the test tube, the gas burns with a 'pop' sound.
