A friend gave me some large jars of Copper sulfate and Alumina
Hydrate which she found in the garage of the house she recently
purchased. The previous owner left a lot of stuff behind for my
friend to dispose of.
As she has left the area my friend is unable to contact her to
find out what these chemicals are used for. Thinking I could use
them, she gave them to me. Problem is, I haven’t a clue as to what
their use is. The jars are sealed, and the material seems to be in
good condition—not cacked. Anyone know what they are used for?
