Laboratory Rule
Students must wear lab coats (white) in the laboratory.
Perfect silence in the laboratory is essential for concentration and successful work.
Keep your table, apparatus, and notebook neat and clean.
Add regents in a proportionate amount, this gives the right result.
Keep the regents in their respective places, do not change the stoppers of the bottles.
Avoid shifting the bottles from the shelf.
Use the waste box for throwing broken glass pieces.
Shake the test tubes while heating, do not throw hot and concentrated acids, specially conc. sulphuric acid.
Pass hydrogen sulphide gas slowly in the solution, it is a very poisonous gas, do not leave the gas stopper open.
Any damage to lab apparatus/equipment will have to be made good.
