Re: Investigating Science equipment
just had a flick through the list of pracs and we had all of the equipment other than the pump and tube. The only thing we needed that we had to order were e-coli plates, effervescent tablets, lollies, biscuits, soaps and a couple of extra rubber mallets

Potassium Permanganate disposal
After the Osmosis and Diffusion prac I have 5L of this to dispose of.
I have read the disposal section of the SDS and wondered if anyone could explain how they dispose of this?
I'm putting on the dunce-hat because it was as clear as mud
Thank you
