An organic compound 'A' is widely used to preserve the pickles and has a molecular formula `C_(2)H_(4)O_(2)`. This compound reacts with ethanol to form a sweet smelling compound 'B'.
Which gas is produced when compound 'A' reacts with washing soda ? Write the chemical equation.

Explanation

Carbon dioxide gas is produced :
`underset("Acetic acid (A)")(2CH_(3)COOH)+underset("carbonate")underset("Sodium")(Na_(2)CO_(3))tounderset("acetate")underset("Sodium")(2CH_(3)COONa)+underset("Water")(H_(2)O)+underset("dioxide")underset("Carbon")(CO_(2))`
