Fume cupboards in senior chemistry labs: With the changes to the Chem course with the Australian Curriculum, and the increased emphasis on organic chem, what are the recommendations for the number
Ammonium thiocyanate: Ammonium thiocyanate is becoming a liquid too fast. I kept it away from the light, but still had no results, and have also bought new jar recently.
Organic chemicals: I have been asked to purchase examples of esters, amides, amines, alkanes and alkenes.
Can someone recommend which of these chemicals are best for school use please?
Water testing: Is it possible to do classroom testing for PFOS and PFOA in water samples? If so, how would you go about it?
Can potassium permanganate waste be neutralised?
Tollens Test: For Year 12 chemistry, the teachers wanted to demonstrate the silver mirror, also called Tollens test. The process goes like this:
Safety Data Sheet updates: Is there any page (web) to get updated M)SDSs as Chemwatch doesn't do that automatically.
Also is it good to have Manifest with PDF SDSs on USB drive?
Eye Dissection: In the SOP for eye dissections I noticed that scalpels are included in your equipment list. Could you please rethink this as an option.
Ferrothiocyanate Fe(SCN)2: We are currently doing a prac called the Effect of concentration changes on equilibrium yields.
chemical storage bottles: Hi, are there any rules about the types of bottles to store chemicals in, in the chemical store room. ie must they have screw lids only or stoppers only.
