You can get HCL at any chemistry supply house, I do not know if you can get Potassium Dichromate any more the Kodak Bleach was changed to Potassium Permanganate because the Dichromate has chromium in it and heavy metals are a environmental hazard. Potassium permanganate is available at chemistry supply hoses as well as HCL. We mix our own bleach from a chemistry house in Massachusetts but we buy a 55gal drum of 50% HCl at a time...

You don't show where in the world you are located. Are you looking for a "small quantity" or enough to fill a commercial processor?

If you just need a litre or two and are in the USA, And don't mind filling out forms to tell the DEA what you want it for...
