the following is​

Answer 1

An acid on reacting with NaHCO3 will release Carbondioxide gas.

Option (B) is correct.

Explanation:

• Sodium bicarbonate will react with acids to release carbon dioxide
• Sodium bicarbonate NaHCO3 is a metal hydrogen carbonate.
• When it reacts with acids it  will form salt of the metal and water and will liberate carbon dioxide.

Thereofre the reaction is:

For exaple if the acid is H2SO4

Acid (  H2SO4) + 2NaHCO3  ------ > Na2SO4 + 2H2O + 2CO2

Thus an acid on reacting with NaHCO3 will release Carbondioxide gas.
