Organic vs Non Organic Chemicals

Hi Everyone,

I was just wondering, is there a list anywhere of "Organic Chemicals" and "Non Organic Chemicals"? I have two bottles set up for disposal but sometimes I am not sure as to what goes in which bottle.

water distillers

Hi Everyone,

I need to buy a new water distiller for science as our old one has finally died. Has anyone bought one lately that they can recommend? It would be nice to get one that doesnt waste the excess water down the sink. Please let me know your recommendations.

Thanks

SMARTBUY

Hi Everyone, I know that we should all be now using SMARTBUY to make any purchases for Science, but I am obviously doing something wrong because every time I search for a product, it comes up "cannot find". Even simple products such as test tubes and copper sulfate. Is anyone else having a...

Re: storage of bromine water

We keep our Bromine Water in a brown bottle, in a sealed snap lock bag, in our Lab Fridge.
Our chemistry teacher has said it "keeps" for alot longer when stored in the fridge.

Phosphorus Red L.R

One of our chemistry teachers has asked "Is there any way of keeping PHOSPHORUS RED L.R dry?"
We have three jars and all are wet inside.
Is it just old or does it come this way?

Thanks

Pheno going cloudy

Another question for you all, this one from a teacher.
What is the problem if you add phenothalein to an acid and it goes cloudy, when it should stay clear?
thanks
