    Really basic chem question, excuse the acid...

    Hi all. I believe muriatic acid is just hydrochloric acid, right? A pal who is a hydrogeologist dropped off a half-filled 55 gal tank he didn't need from when he cleaned out his shop.

    I couldn't see the percentage anywhere on the barrel.

    Before I use it in place of my hardware store MA, I just want to confirm that it's a) same diff and b) likely to be the same concentration 34% as the store-bought stuff. I will use a third to test first, bUt just thought I'd check to see if anyone happened to know.

    Thanks in advance!

    Probably same concentration.

    "Bulk industrial-grade is therefore 30% to 34%, optimized for effective transport and limited product loss by HCl vapors."

    You won't need to buy acid for a while
