You should be able to get it from wherever you buy the rest of your chemicals. It's one of those ones I don't keep a stock solution of. I just make it up to whatever concentration is required for a specific prac. I don't think it gets used very often...

I have a couple of bottles of 0.25M which are used in a Yr11 Chem prac Rate of Reaction. It's also good for iodine spills. Just rinse in sodium thiosulfate, then rinse again with water.
