Hi Everyone

I was just asked for calcium metal, we don't have any. It is to do the same prac as has been talked about above. I'm just wondering does everyone have calcium in there in chem stores and if you do how do you store it. Any info will be greatly appreciated.
Cheers

Thanks for putting that up Jazz
Just one question. On page 14 it says that the corrosive cupboard should not be in the chemical store? Have I misinterpreted that? I wouldn't have any where else to put my corrosive cupboard.

I use 1M sodium sulfate with a few drops of universal indicator so the columns go green, pink and purple, everyone likes it but the stoppers around the electrodes have perished but I just cored new ones and replaced them. A bit of mucking around I know but all is good.

Good Morning Everyone, Feel like its been a while since I had a chance to jump on here, Hope you're all good or at least well and careful. Does anyone have Joules calorimeters? For the first time in 7 years in this job a teacher has asked for ours but then we looked inside them and he is suspects th...

we purchased the SciList program and if I ever get time I was going to have a go at using the chemical register that came with that. Has anyone else already done this by any chance? I wonder if its possible to import your current list directly to the Scilist program.

Its very scary isn't it. My mum is in Lithgow and my brother in Springwood. My childhood home has been destroyed although my mum moved into town some years ago. I feel so sorry for all the poor people involved in this and hold the firefighters in the hghest esteeem. I pray they are all safe.

Hi
I know I've read on here before but can't find it now. Should strong acids be stored in glass or plastic, for some reason I think its plastic but when you buy the stuff it comes in a glass bottle? Thanks for any help.

yes i did do several titrations. I was going to just throw it away but I thought its just as easy to fix it as it is to start again.After a cup of tea the fog cleared and I was able to calculate what I needed. I have a few bottles (all different concentrations) that have been made up incorrectly (no...

HI
i have about 1.7L of 0.632M Naoh. I want to make it up to a 1M concentration. How do I work that out? Sorry brains gone to mush.Was trying C=nv and n=m/mr
got myself all fuddled
Thanks Krysia

HAPPY BIRTHDAY SMILEY
Hope you have great day and get spoilt rotten.

Actually can anyone tell me if having our SDS'S printed in colour is mandatory? I'm trying to get access to a colour printer and this would help my argument.

Hi Guys
Is anyone else having trouble with Chemwatch this week or is it my computer?

Hi
does anyone know how long we keep risk assessments for. I have read 30 years and 7 years. Is anyone sure?
Thanks Krysia

Hi Everyone I haven't had time to get on here for most of the term. Hope all is well with everyone. This is time consuming I guess but what I have done a few times with crubiles that have been stained is put some water, sand and a magnetic stirrer in the crucible and leave the on the hot plate/stirr...

Hi Cindy
I had the same problem. I replaced the rubber stoppers that the electrodes go through and they haven't leaked since.
