a water insoluble substance x on reacting with dilute H2 S o4 released a colourless and odourless gas accompanied by brisk effervescence.. when gas was was passed through water the solution obtained turn blue Litmus red on bubbling the gas through lime water it initially became milky and the milkiness disappear when the gas was passed in excess identify the substance X and write the chemical equation for the reaction involved ??

Sodium carbonate (substance X)on heating with sulphuric acid we get sodium sulphate , CO2 and water
Na2CO3 +H2SO4 ---->Na2SO4 +CO2 +H2O
ON PASSING CO2 gas to lime water it turns milky white due to formation of CaCO3.
Ca(OH)2 +CO2 ---->CaCO3 +H2O
IF EXCESS OF CO2 IS PASSED, the milky white colour disappears due to formation of calcium hydrogen carbonate.
CaCO3+CO2+H2O---->Ca(HCO3)2

It might be a metal carbonate like CaCO3
thank you riya✌
your welcome but listen CaCO3 was an example of a metal carbonate you can also use Na2CO3 as suggested by Niki
okay...thank you very much✌
