Question

A gas is librated immediately with a brisk effervessence when you add acetic acid to sodium hydrocarbonate powder in a test tube . Name the gas and describe the test that cofirms the identity of the gas

Answer 1

CO2 IS THE GAS WHICH EMERGED WITH EFFERVESCENCE

CH3COOH+NAHCO3=CH3COONA+H20+CO2

IT CAN BE TESTED BY SLAKED LIME TEST.WHEN PASSED CO2 OVER SLAKED LIME IT BECOMES MILKY DUE TO FORMATION OF CaCO3
