Question

Name the gas evolved when dilute sulphuric acid reacts with sodium carbonate. Write the chemical equation for the reaction involved

Answer 1

H2SO4(aq) + Na2CO3(s) = Na2SO4(aq) + H2O + CO2(g)

So, when dilute sulphuric acid reacts with sodium carbonate, carbon dioxide gas is evolved.


HOPE THIS ANSWER HELPS YOU !!!!!

Answer 2

Answer: Gas evolved during the reaction of sulfuric acid and sodium carbonate is carbon dioxide ( $CO_2$ )

Explanation: When sodium carbonate reacts with sulfuric acid, the reaction follows:

$H_2SO_4(aq.)+Na_2CO_3(aq.)\rightarrow Na_2SO_4(aq.)+H_2O(l)+CO_2(g)$

The gas evolved is Carbon dioxide which is seen by the formation of bubbles.
