Question

When ethanoic acid reacts with sodium hydrogen carbonate, the salt ‘X’ is
formed and gas ‘Y’ is evolved.
(a) Identify ‘X’ and ‘Y’.
(b) Write balanced chemical equation of above reaction.
(c) Describe a test to identify the gas ‘Y’ evolved.

Answer 1

X = ch3cooNa
Y= CO2





pass CO2 gas through lome water so ot turn lime water milky

Answer 2

When ethanoic acid reacts with sodium hydrogen carbonate, the salt ‘X’ is
formed and gas ‘Y’ is evolved.
A]

X---- SODIUM ETHANOATE. [CH3COONa]
Y----- CO2
B]
CH3COOH +NaHCO3 --------->CH3COONa+CO2+H2O

C]CO2 GAS can be tested by passing into lime water, which turns into milky white.
