A student added sodium hydrogen carbonate solution in ethanoic acid taken in a test tube and the gas evolved was tested with a burning splinter. Write the chemical equation for the evolution of this gas and its effect on burning splinter.

Text Solution

Verified by Experts

`CH_(3)COOH+NaHCO_(3)rarrCH_(3)COONa+H_(2)O+CO_(2)`
Since `CO_(2)` is not a supporter of combustion, the burning splinter will be extinguished.

Write chemical equations for the reactions of ethanoic acid with sodium carbonate

Ehanoic acid was added to sodium hydrogencarbonate solution and the gas evolved was tested with a burning splinter. The following fourobservations were reporte: The gas burns with the opsound and the flame gets extinguished The gas does not burn but the splinter burns with a pop sound The flame extinguishes and the gas does not burn. The gas burns with a blue flame and the splinter burns brightly. The correct observation is reported in,

When you add sodium hydrogen carbonate to acetic acid in a test tube, a gas liberates immediately with a brick effervescence. Name this gas. Describe the method of testing this gas.

A gas is evolved when ethanol reacts with sodium. Name the gas evolved and also write the balanced chemical equation of the reaction involved.

Four students added a small amount of ethanoic acid to sodium hydrogencarbonate. The gas evolved was tested for its behaviour with burning splinter and lime water. They reported their observations as given on the next page. The correct observations have been reported by student:
