A salt X is formed and a gas is evolved when ethanoic acid reacts with NaHCO3.Name the salt X and the gas evolved. describe any activity and draw the diagram of the apparatus to prove that he evolved is the one which you have named. Also write chemical reaction of the reaction involved.

salt X is CH3COONa
and is known as sodium acetate
reaction
2CH3COOH + NaHCO3 =CH3COONa + H2O + CO2
the gas evolved is carbon dioxide
to check this gas
pass this gas through slacked lime

X is sodium ethanoate.
Gas evolved is carbon dioxide.
Activity:
Set up the apparatus as shown in the figure.
Take a spatula-full of sodium hydrogencarbonate in a test tube and add 2 mL of dilute ethanoic acid.
We observe that brisk effervescence of a gas is produced in the test tube.
Now pass the gas produced through freshly prepared lime water.
It is observed that lime water turns milky. Only carbon dioxide gas can turn lime water milky. So, this activity proves that when ethanoic acid reacts with sodium hydrogencarbonate, then carbon dioxide is evolved.
