Name the gas evolved when dilute HCl reacts with sodium hydro-carbonate. How is it recognized?

Academic Chemistry NCERT Class 10

The gas evolved when dilute HCl reacts with sodium hydro-carbonate is Carbon dioxide (CO₂).

Test for CO₂: On passing this gas through lime water which turns milky. On passing this gas in excess through the milky lime water, it would become clear again.
