Hydrochloric acid - Where to Buy?

[rahimlee54]

All the big chemical houses will sell you whatever grade and concentration you would like. EMD, JT Baker, Sigma Aldrich. Those are the 3 we use at work. Concentrated HCl is 12.1 N which is really strong, wear some gloves.

I used to get it for totally not making explosives when I was a kid at pool supply stores or home depot during the summer.

You know anybody in an academic science field??? I used to get it from my H.S. chemistry teacher, and then a friend who was a professor. Used it to clean masonry and they were able to obtain higher Molar concentrations than I was.

Depending on what concentration you need (I have no idea) this is the best way to get it.

seconded! I would also suggest that you work outside or in a fume hood; when reacting, it usually fumes like crazy

Thanks guys.

Sigma Aldritch sells all kinds of chemicals.

Why not use Ferric Chloride? It's called PCB Etchant and you get it at Radio Shack.

Hydrochloric acid is cheaper and should be widely available as muriatic or pool acid in 23% solution. It think it costs under $10 per gallon, while Ferric Chloride for the same price you can get 16oz.

This is what I found in the last couple of days.

Ok I want to see some pics of your stuff after you etch it, want to see the difference in the etch, if there is any.

Marko, I hope you don't mind if I hang my question on this thread: I have ferric chloride in powder form (Radioshack doesn't have it in Hawaii and they don't let the liquid stuff on planes...). Can anybody please tell me what the best ratio for mixing this with water is? How much powder per ounce?
Thanks,

Stefan
