Copper (II) Sulfate 5-Hydrate Powder, 500g - Laboratory-Grade - The Curated Chemical Collection

Works great on the horse feet I've used it on.

Quick shipment

Great for thrush

I used this to form part of an electroplating solution. Works great. No noticeable impurities.

Very good product that has a great concentration and dissolves well in warm or cold water.

Does what it should.

We needed some copper sulfate for liquid resisttors, so the reduced price for a still good-quality chemical powder is greatly appreciated. The product is exactly as described.

I have no issue with the chemical itself. I have more problems with the lack of safety involved in shipment. There is no seal inside the bottle and no plastic covering on the outside. So, it can pop open during the whole shipping process, which has happened to me before on other bottled orders. That is a danger to the person packaging this, the delivery driver, and to whoever is receiving this order. Especially since it is harmful if swallowed, causes skin irritation, serious eye irritation, and is very toxic to aquatic life with long-term effects.
