Question

Name the gas evolved when dilute HCL reacts with sodium carbon and hydrogen carbonate

​

Answer 1

Explanation:

The gas evolved when sodium hydrogen carbonate reacts with HCl is Carbon dioxide. The gas can be identified by passing through the lime water. when carbon dioxide passes through the lime water, it turns milky due to the formation of calcium carbonate which is insoluble in water.

Answer 2

Answer:

CO2 (carbon dioxide)

Explanation:

when sodium hydrogen carbonate (NaHCO3) reacts with dil hydrochloric acid (dil.Hcl) it produces corresponding salt (NaCL) and water (H2O) with the evolution of carbon dioxide (CO2)
