Question

show acid reacts with metal carbonate and metal hydrogen carbonates to liberate carbon dioxide (activity) Aim, Material, observation and conclusion

Answer 1

Aim : To show that all metal carbonates and hydrogen carbonates react with acids to give a corresponding salt.
Required Materials :

Two test tubes

Sodium carbonate

Sodium hydrogen carbonate

Two holed rubber stopper

Thistle funnel

Stand

Dilute hydrochloric acid

Delivery tube

Calcium carbonate (in a test tube)

Procedure :

Take a test tube A with 0.5 gm of sodium carbonate.

Close the test tube A with two holed rubber stopper.

Insert a thistle funnel through one hole and insert a delivery tube through the other hole.

Pour 2ml of dilute HCl to the test tube A.

Do the same as above with test tube B with sodium hydrogen carbonate. Observation : Carbon dioxide is released from test tube A and B.
