Summarize the key instructions and statements from the Supervisor's Report for a practical chemistry exam.

Here is a summary of the instructions and statements from the Supervisor's Report:

11. Supervisor's Report Forms are provided separately and a completed form must be enclosed in each envelope of scripts.
12. The Chemistry teacher must perform the titrations for Question 1, recording figures to at least one decimal place and verifying them. This ensures consistency with candidate titrations and prevents unfair penalties.
13. Any difficulties encountered by candidates should be reported, especially if they wouldn't be evident from the scripts.
14. Candidates must be reminded that chemicals are dangerous if not handled properly. Before the practical exam, the following safety statements should be read aloud:
    • Chemicals are dangerous and must be handled carefully.
    • Report any unusual sensation to the invigilator immediately.
    • If any chemical enters the mouth, wash it thoroughly with plenty of water.
    • Wash hands thoroughly after handling chemicals.
15. Appropriate arrangements are expected to be in place to prevent any accidents.
