Re: Testing the "freshness" of acidified Potassium Dichromate
Potassium Dichromate acidified becomes Chromic Acid, which is banned in all DET schools. Best to put in the collection waste storage area to be picked up, at some time.

Re: Chem Store Usage
You could go to your OHS Committee. Or phone Dr Pam Veivers at PSA (if you are a member) But I feel sure they will help you any way. On 02 9290 1555. Pam will know what the legal bits are.
Do hope this helps
