nitric acid
silver nitrate
barium nitrate
ammonia
sulfuric acid
Iron (II) sulfate
hydrochloric acid
sodium fluoride
sodium hydroxide
potassium thiocyanate
Acidified dilute potassium permanganate
Lead nitrate
Potassium iodide
these chemicals will be use in the practice,
and i have find a lot of general rules for safety:
1. Never use a product that doesn't have a label to reference.
2. It's a good idea to visit a product manufacturer's Web site and download the material safety data sheet, which provides information on safety and health issues. (try to visit MSDS but there is only 5 attempt)
3. Don't mix chemicals without specific authorization from the formulator. Mixing incompatible products can render them ineffective, or it can produce toxic materials that present unsafe exposure conditions.
4. Always use personal protective equipment. Protect your eyes and hands from exposure to harsh chemicals; gloves, goggles or whatever is appropriate.
5. When pouring chemicals, pour concentrates into the water and not vice-versa. This way whatever splashes out will be primarily water and not concentrated chemicals.
6. If a little bit will do the job, mixing more concentrated chemical won't do it better. At best, that is a waste of time; at worst you may ruin something or cause physical harm.
7. Never pour chemicals into an empty, unlabeled container.
8. Don't store flammable chemicals near a source of heat.
9. Pesticides, fungicides, etc. always must be stored in a safe and elevated position.
10. Ventilate when engaging in cleaning or other applications using strong chemicals, especially dry solvents.
Always test a product on an item being worked on in an inconspicuous location before applying an item overall.
i am afraid that some of chemical such as hydrochloric acid, nitric acid and sulfuric acid
are not covered in these general rules,
i need to know which one of these chemicals have some special properties(like shouldn't mix
with specific chemical etc.) that doesn't covered in general rules
and i should pay more attention of?
and a small qestion: if the molecular formula are asked, what should i write for Acidified dilute potassium permanganate.

Google MSDS - there are pleanty of sources where they ce be seen without limits.
if the molecular formula are asked, what should i write for Acidified dilute potassium permanganate.
I think I have seen this question before...
Try KMnO4/H2SO4
