Hi Jazz

so youre saying you just add a bit of carbon in along with the iron filings and the Copper oxide?

I heat for a l o n g time, in Pyrex boiling tube, until it was read glowing hot.

But no go
is there an optimum ratio of the Cu O to Fe?

Thanks Graeme. Perfect Just what I needed

David, I make my own schultz
Zn Cl sat soln then cooled.
The add drop by drop the I/KI soln

its yr 12 chemistry doing testing for cellulose, starch etc

The dark blue positive with schultz's soln on cellulose, and the Iodine /KI solution black positive on starch. Can anyone provide the reaction equation for these please?

Thanking you

No-one had better bring me a dead bat

But are quite pricey I would love my prep area to be wall to wall antifatigue mats. Actually. I use a large one at my washing up sink. If there are any drip...

Krysia Chemwatch is like the governing Continent. ChemFFx is like country within the continent. Ok that sounds odd. ChemFFX is a smaller part of ChemGold 3, just has a few less features, but is suitable for all purposes. That m,ake sense? or not? ok I am of to have my morning coffee and hopefully wa...

laughing so much I have a stitch SO very funny and so very true!
Would anyone swop it for a boring desk office job?
(assuming same pay rates?)

odd for sure.

I am sure that we all have a few. I know I have some of my own :crazy: But this morning reminded me of one of my teachers foibles/quirks He asks me to wash his whiteboard erasers. That is: take it out of the plastic case, soak and wash it (numerous times to get the ink out), dry it out & reglue ...

I havent seen a flier yet
