Hi mtg...do u just place the liquid into the specimen jar for them to form a crystal or do you dry it our first then place into jar...Sorry for asking but I have only done the CuSO4 before and not the other solutions. Thanks

Hi everyone...Im in need of help/suggestions...For science week next week the teachers want to make crystal gardens and have asked me to make larger sized crystals for them to place in a sodium silicate solution. I have made up solutions of iron chloride, manganese sulfate, copper chloride and iron ...

I have always been told to go by what CSIS says until the new books come out (whenever that may be) as I also have found riskasses is different to CSIS....

Hi AnnNos..what section in the CSIS book does it have the quantities that are allowed to be stored on the premises...Thanks in advance

Thanks Debbie

Here is a list of duties I do you are welcomed to use...I probably do more than this

Thanks Lyn...This teacher is a very capable teacher in classroom management and discipline. This is his 2nd year with us in the science department and does ask the science trained teachers for help when needed in which they are happy to do....Its just that they all asked me what is the highest molar...

Afternoon Everyone

Just a question...What is the highest molar a non science trained teacher (who is currently re training)can use?

Thanks heaps

I have bought some of the plastic dropper bottles from Serratta due to kids contaminating the chemical by placing different dropper in and the new teats not fitting properly. So far so good. Not all chemicals can go in them due to some having to stay in darker bottles. Hope this helps

Good morning everyone

Just wondering do you keep your cobalt chloride solution in a clear/plastic dropper bottles or a brown glass bottles

Thanks heaps
Michelle

Hi
I use a website called Mass Molarity Calculator Sigma-Aldrich for when I have hard solutions to make. https://www.sigmaaldrich.com/chemistry/ ... lator.html
I just click on one of the links to work things out.
Hope this helps

Thanks westlab

I bought mine off Ebay in bulk and were cheap ...they are great and work fine...just make sure they are the same
