Re: Annual Chemical Stock Take
Hi all, Just wondering if any of you have been asked to do a chemical stocktake for the entire school? Or do you just record science? I've been trying to find some information on this but can't find anything other than forums but I have read somewhere that you don't need to record the chemical if it...

Re: Limewater
Hi
this might be a dumb question, but I followed the instructions in 'the laboratory', so when the solution settles am I meant to decant that liquid into a bottle? or just do it now when its a milky colour?
thanks!

Re: Phenolphthalein Agar
Heya.
If using the dropper trays (or any trays), does the agar come out easily enough or does it stick to the edges?
Thanks

Re: egg membrane
Hey,
Just wondering. I've had the eggs in from the beginning of the day, how long does the process usually take to complete?
And is it bad if I leave them in the fridge still in the vinegar over the weekend to complete? Or will this just further break them down?
Thanks!
