Question

write an activity to show that all metals carbonates and hydrogen carbonates react with acid to give a corresponding salt.
​

Answer 1

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

Required Materials :

1. Two test tubes
2. Sodium carbonate
3. Sodium hydrogen carbonate
4. Two holed rubber stopper
5. Thistle funnel
6. Stand
7. Dilute hydrochloric acid
8. Delivery tube
9. Calcium carbonate (in a test tube)

Procedure :

1. Take a test tube A with 0.5 gm of sodium carbonate.
2. Close the test tube A with two holed rubber stopper.
3. Insert a thistle funnel through one hole and insert a delivery tube through the other hole.
4. Pour 2ml of dilute HCl to the test tube A.
5. Do the same as above with test tube B with sodium hydrogen carbonate. Observation : Carbon dioxide is released from test tube A and B.

Result: All metal carbonates and hydrogen carbonates react with acids to give a corresponding salt.
