K2CO4 is not a valid compound, but K2CO3 is. Silver nitrate reacts with potassium carbonate to form a white precipitate of silver carbonate. The specific reaction that takes place is AgNO3 + K2CO3 = AgCO3 + K2NO3

What are the precautions of test tube holder?
If you are heating a test tube, point it away from yourself and others. If you need to place a test tube into a hot water bath, or take it out of a hot water bath, you need to use a test tube holder and not your unprotected fingers. Do not leave the test tube holder attached to the test tube while it is heating, as this will also heat up the test tube holder. If a test tube breaks, tell your teacher, and clean it up with a broom and dust pan. Don't pick the glass up with your fingers.
