which acid is used to produce brisk effervescence of CO₂ when reacted with CaCO₃

Open in App

Solution

In a conical flask, when hydrochloric acid is dropped on marble chips ( CaCO₃), carbon-dioxide gas get evolved which is passed through delivery tube and gets collected from the upward displacement of air in a hood.

The chemical reaction occurring there is shown as follow:

2HCl + CaCO₃--> CO₂ + CaCl₂ + H₂O
