thanks so much Labbie.
I've been using Risk Assess for labels (it's so easy and quick), but as yet, it doesn't do mixtures, so I got a bit stumped.
I should have gone straight to ChemWatch myself.
Appreciate your attachment... saves me from locating it.

Re: disposal of oxalic acid
wow, Graham, Thanks for the information. I've put it in a bucket of water (the saturated oxalic acid is in a 150 mL beaker, and crystalised), and have added a sprinkling of sodium carbonate. I have no idea how much oxalic acid I added, as I read that to make it saturated, you just keep adding. I sus...

I added sodium bicarb....... all that happened was lots of fizz, but the pH remained 4.0 (pink colour)

disposal of oxalic acid
Hi everyone,
I have made saturated oxalic acid (about 100mL )for a yr 11 experiment. The CSIS appendix D says it's ok to put it down the sink after making it pH: 8-10.
Could anyone please tell me which chemical I add, and how much?
Thanks heaps.
Kirin

Re: Microscope repair / training
I was just talking to my science teachers about Microscope service and cleaning this morning.
They said to search for one, so it can be included in next year's budget.

Re: Chart storage
I used a large flat screen TV carton. Measured the width of the posters and cut. I cut the back out of the other side and slid it into the longest one. Glued it in place and painted it. A piece of flat steel on an angle goes in - holds about 80 A1 size posters. Larger ones go into a smaller flat sc...

Re: Separating funnel

Re: hello
Hi there everyone, I'm also new to the Science Department. I'm employed as the Lab assistant, but have no prior science/chemical knowledge. I'm actually a primary school teacher, but found casual teaching not quite my 'cup of tea'. I applied for this job, got it, and started at the beginning of this...
