Hi all,
Does anyone know where I could buy some sodium fluoride......ASAP? In the Newcastle area.
My teacher wants some for tomorrow.................I have phoned a few pharmacies with no luck.
Otherwise she'll have to wait...............

Re: Sodium Fluoride
Sodium Fluoride: DG 6.1 Highly Toxic with severe chronic effects. Known sensitiser. Contact with acids liberates very Toxic gas. Not required in curriculum.
This has been on a banned list of chemicals for the NT and South Australia schools for quite a while now. I don't know what the situation is in NSW. You will not acquire this chemical from a pharmacy. Perhaps the teacher needs to source their own supply from a chemical company and provide a comprehensive risk assessment for its use before it is purchased. It would be a teacher only demonstration. Definitely not for student use. Quite frankly I wouldn't be handling that chemical myself.
There is still a prac in Pearson 10 text - "Halogen precipitates" - that lists potassium fluoride (another chemical on the banned list). Teachers are a bit miffed when they are told that they can't have certain chemicals. But a banned listed chemical is a banned chemical.

Re: Sodium Fluoride
Hmmm ...just looked up CSIS , it's Yr11/12 .
Apparently it produces highly toxic fumes of Hydrofluoric acid when added to concentrated acids .
Note: Hydrofluoric acid is Banned chemical .
Just looked to see if we have it . We did but it had a green sticker on it .....fixed that .
Maybe you can borrow some from another school .

Re: Sodium Fluoride
RiskAssess has the solid as Yr11/12 but solutions as Yr 7-12.
I think it was part of a prac in the old chem curriculum??

Re: Sodium Fluoride
Thanks everyone!
It is for year 12 Chem "investigating an equilibrium system" to be used with iron III thiocyanate, 0.0005M and silver nitrate, 0.1M.
I'll let her know..........

Here's the one we did for that topic - worked well and no fluoride.
