Question

Procedure :
1. Take a solution of calcium chloride (CaCl) in a conical flask.
2. Take a solution of Sodium Sulphate (Na SO2) in a test tube.
3. Tie a thread of test tube and release it in the conical flask.
Make the conical flask airtight by putting a rubber cork.
5. Weigh the resulting assembly together with the balance.
6. Tilt the conical flask and mix the solutions in the conical flask and test tube in each other.
