Answer:
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.

Answer:
Take two beakers one containing Hcl acid and the other containg hydrogen but its not acid for ex.., alcohol..... This show that acid get dissociate d as H+ and Cl - ions and these ions are responsible for the conductance and alcohol does not. So all acids has hydrogen and all hydrogen containing compounds are not acid
