    5 Pounds - Copper Sulfate Pentahydrate Powder - 99% Pure
    Apr 18, 2021
    Fair quality
    Good bargain. I was about to crystalize some, but I noticed that the solution was somewhat cloudy. I left it sit for some time, and the precipitate formed. I assume it isn't as pure as they state, but for a skilful chemist simple filtration isn't a big deal.
