I am trying to find an msds for Fire Kill , (Its a fire retardant,) but without success #-o I cant find it on Chemwatch either, but that may be more my poor user skills than anything heres a link to a newspaper article for the product http://www.borderwatch.com.au/archives/1894 Thanks :) R-S

Hi Linda :-) We send out the Risk Assessment with the pracs. No print in sending out an msds, they have no time to look at them just before the prac, but they need to look at the RA, and use that. However, For the senior chemistry classes, I always send in the One Page Summary for each of the chemic...

great

anyone have the prac in a pdf etc?

we have done both the measuring cylinder, and the coke bottles. Both are really good in different ways. We usually do one onf each.. side by side. Just make sure that if youre doing coke bottles...AND want to do repeat reactions.. just have a steady suply of coke bottles on hand...as I said before t...

The reaction generates a lot of heat. You would have to be very sure that your flask is a top grade glass... ans even then I would NOT risk it in glass case of breakage.

We use PET drink bottles, but the heat shrinks the bottle every time its used for a reaction

tell me more Sunray??
is this in conjunction with using a video--> DVD recorder?

My teacher want to know ( re the green capsicum prac).. are the different concentrations measurable ( rather than merely subjective)?

Just a reminder to make sure to set the new DVD up into Chapters, or else you may regret it later on! Especially if you have say, a video with 20 x 10 minute programs on it.... you will want to just be able to press the "next" button on the DVD. Rather than struggle to locate the start of ...

thats very interesting.
I shall just buy the green ..dont want to get too fancy to start with

Thanks to the person who told me that there was a thread on Aquariums :D Love those pics..wow! Here are a few pics of my cichlids Cichlid Fish Acei. Oct 2010 035.jpg Cichlidmeachromis aureus..

Thanks so much for the prac Bindibadgi:) and the potato & silver beet ones? anyone have those as well??
I have never ever done the liver one, as I could not face the cleaning up afterwards!

I fancied a career in rocket surgery.
But wasnt smart enough

bindibadgi

I dont know that prac.. can you post it here please?

Teacher would like an enzyme prac to demonstrate the effect of substrate concentration . Has been using milk and rennin, but its not really very effective at identifying an end point Was thinking maybe something with amalase or lipase? heres hoping that you clever people have something up your sleev...

Not much difference really between the two then Ian.

Whoever said that screened methyl orange is easier to use than the regualr MO, are telling porkie pies! (just my opinion!)

Thanks Rae.. yes, it all helped

Please help! Our chem students are doing titrations using screened methyl orange.. but the colours are mutating as we speak!

I am wondering if regular Methyl Orange has the same pH end point as the Screened Methyl Orange?

Yes thanks you Rita and Ian.... makes sense now

Oh yes.. go on.. do it!
A computer mouse, and a picture of a cat.. in the trolley.. ready for the prac!

And wear leather or thick cotton gloves and eye protection as you "brute force" it.

Clear as mud guys

can you break it down for someone like me please?
so "s" stands for.......?
