Question

A metal carbonate X and a metal bicarbonate Y on reacting with an acid gives a gas which turns limewater milky.
a.) Identify the gas, compound X and Y.
b.) Write the chemical equations for the reaction of X and Y with the acid.
c.) Write the chemical equation on passing the above gas through limewater.

Answer 1

The gas passed is CO2

Answer 2

A. X-Na2CO3

Y-NaHCO3

GAS IS CARBON DIOXIDE

B. Na2CO3+2HCL=2NACL+CO2+H2O

NAHCO3+HCL=NACL+CO2+H2O

C.CA(OH)2+CO2=CACO

3+H2O
