CAS No.: 7632-00-0 2 Pound, Manofohm

Great price, great product. Purity as advertised. Shipping took almost 3 weeks, but I'm not holding seller responsible. I ordered during holidays and had a couple of other packages from the US take longer than from China. I will definitely order this again and likely other products from man of ohm. (As in ohm units of resistance? )Packaging was nice- secure, sturdy, with label with relevant Chem properties, nice because i grow tired of looking up molar mass or density over and over again. You'd think I'd sure this down, but every time I'm sure i won't forget.... so nice touch to have these on label on product.

Prevents rust from forming in my plasma water table.

great price and fast shipping...A++++
