I am replacing all the MSDS folders in the school with SDS folders basically this entails just changing the Presentation sheet on the front cover and the spine Ihave looked on internet images, but no success. Anyone have a template they are happy to share? Doesnt matter if its Word, Publisher or pdf

Hi Coolest Guy in School

welcome to the menagerie

Hello Pinky I did mine about 8 yrs ago. (cert III lab Skills) Was definately worth doing . For me, some was difficult, some was old ground revised. The thing that pressured me was the time issue.. working full time and holding downt he fort with hoem and family as well. But I'm glad I did it. Once y...

what is this Sunray? I dont have the working in science book. I have my own draft doc for SOPs

we have been sucessful with several tasks at stations: Set up a circuit, gets marked /yes/no depending if light comes on. then dismantle again& put components back into box (those ones are near teachers bench so she can view). Or take readings from the Am, V, use resistors etc Reading a series o...

Good to have you back with us Noona

Have a great time David
Take us with you!!

Know what you mean lada. It sort of 'checks' the teachers calculations are correct for their students

Thank You ! ThanK YoU Thank YoU Guys
Ia m one very happy little vegemiter now

I appreciate all your brain strain on my behalf

Teacher doesnt have time to do the standardiseations, and its just been expected that I do the calcs when labelling the bottles as well.

Thanks for this "brains trust"
I await a definitive answer ..pretty please

eeeeeekkkkkk! this is getting scary. I have to have the correct result for the molarity of the Na OH, as after the studetns have done their individual titrations, the teacher will ask me for the precise molarity. (its a titration assessement) is this becasue of the 2Na OH neutralising with the one o...

Thanks David. That too helps

Thanks for that link. Says a science laboratory. Are we sure it was a primary school? And I wonder what concentration and type of acid it was and how it happened. Curious arent I?

many thanks everyone for your assistance.
so 0.99 M/L it is

and I will keep that useful work method sheet for future reference

Ok. that gets me out of trouble
So where does the 2Na OH neutralising the 1 oxalic acid come into play at all?

Can any of you very clever people please help me with these titration calcs. been so long since I have done it i am confused. :? I have just done titration in order to standardise Na OH. I used oxalic acid as the standard, at 0.0500 M/L My Na OH is approx 0.1 M/L. the tect book says that 2Na OH + H ...

is there a link to the news item?

Can you give them a telling off (the teachers) for mis-using equipment?

Its akin to taking a spatula to stir a solution, but dipping your fingers in instead

asperilligus niger. Nice one!
Yes, I havent the time to go gram staining LOL.

The fungus is impressive.
Yes its definately a case of "you know youre a lab asst when...." hee hee.

ok have filled it in an pressed the 'done' button. I assume thats all thats required?

Thanks Smeee
