I would be interested if any one had spares too. You cannot buy them from the publisher and I could do with 2 as well.

Yes I'd be interested in that too!

And Wollongong city council did it too. They formed side of road barrier piles that had asbestos in it. Councils have to purchase there material from somewhere too and if it has asbestos surely it should be the supplier who is in trouble.

The funny thing is, Adrianna, it was the road where I grew up that was one of them. In there defence I think they purchased road base/ recycled cement from somewhere that had asbestos in it. I'm sure it wasn't deliberate.

use 0.1M solutions and make up copper chloride, lithium chloride, strontium chloride, sodium chloride, potassium chloride and barium chloride.
The flames will be green, pink, dark pink, yellow, lilac and green Have fun experimenting.

FYI Quote taken from Nature.com Thought this was interesting "It is the International Union of Pure and Applied Chemistry (IUPAC) who deal with questions of nomenclature and naming when it comes to chemical elements and compounds. And so when IUPAC decided that element 16 should be spelled as '...

I agree Kathryn. Just the fact that it has been brought to his attention with the possibility I would have thought would make it a duty of care.

I'm sure CSIS was written before there was a thought that the talc could possible contain asbestos.

I just looked it up under the 'f' and there was certainly plenty of options. I don't know what molarity was required but I couldn't see a problem. It also included 'ph' options too.

Try sulfuric acid?!

As in its rusted??
I use a cream cleanser and a green scratchy scourer.

My chem teacher uses C1V1=C2V2 for any concentration calculation.
so:
0.1%x 500 = 80% x V2

So I think the volume would be 0.625ml in 500ml

I have about 6 of these and I love them! Easy to manoeuvre, light weight, plenty of room, easy to clean. Seem to be chemical resistant. Will negotiate uneven ground.

no I bought Bromine. No idea there was a restriction!

I think I bought 100ml a couple of years ago.

I have Bromine in a bottle not ampoules. I think it is easier to manage. Never liked ampoules.

1ml to 200ml water. Make sure you do it in a fume cupboard and wear all your ppe.

Good Morning All, We are trying to replace our window coverings in our labs. I have always assumed that we need to have fire retardant fabric in any blinds/curtains we have on the windows. Does any one have a copy or knows where I can find the safety standards that refers to window coverings? Many T...

Pretty sure this I had one which the on off switch went on. I had our maintenance man look at it and couldn't find the fault but another fellow here who loves electronics pulled it apart and found a fault which he couldn't repair. Pretty sure it was a lightning strike that blew it up til then I had ...
