When I trained people we would get them to mix chemicals up, starting with a salt solution, then getting to bigger things. Doing the waste as it came in from the classrooms, checking the dropper bottles, before putting away. Writting out an order, (It was put into a book) I always worked with them, ...

Great Idea Rosalie.

Yes I thought it was Labbassistant, indeed, can not remember where I read it but yes yes

Yes bigmack they do this from time to time, so we WHERE told I'm retired now, it is mainly for the big company's that have much larger bottles then us labbies. Some company's have 20 Litre's of the stuff.

Oh Merilyn do take care, not a good break from school, for you.

Welcome back, how are you all keeping, dry???

I can relate to that Merilyn1 & Bigmack,

Or use the plastic dropper bottles?

Excellent Super Bug, what was the Molar you had in them?

Oh Bigmack thank you

Is this place ISSCO CLOSED?

Thank you again Bigmack

Good question Rosaliel

You are most welcome Rosaliel

I have done a search but haven't found my answer... I have a sample pot (specimen jar) of ferrous ammonium sulfate (label printed by previous labbie) and the hand written chemical formula on it is wrong. It is a very pale green salt. Would this be iron II or iron III? Is there a way to work it out? ...

I have tried & Tried to undo this, but it will not let me. The Minute I did it, I realised. So Sorry

Ammonium iron(II) sulfate Chemical compound Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH₄)₂Fe(SO₄)₂(H₂O)₆. Containing two different cations, Fe²⁺ and NH₄⁺, it is classified as a double salt of ferrous sulfate and ammonium sulfate. Wikipedia Formula: (NH₄)...

Thank you Alice,

Hi Harvey, There is also a facebook page called Labbies. We have a lot of labbies from Vic, that you may be able to help. Two questions to answer before joining up. Are you a Labbie, just put NO Repairer of science equipment. Can you help others, thank you

WOW thank you
