Melting #2: Copper (II) Sulfate (Confusion)

The last time we melted sulfur, and it was really fun (except for cleaning the test tube). Now let’s melt something else, what about Copper Sulfate?

Copper (II) sulfate is the inorganic compound with the chemical formula CuSO4. Older names for this compound include blue vitriol, bluestone, vitriol of copper, and Roman vitriol. The pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue.

Melting Point: 110 °C (230 °F)

Sulfur’s melting point is 5 °C higher (which means they’ll melt about the same time). So let’s get started.

It looks impossible to melt it because the sulfur is more (soft) like a powder, but this one is tiny crystals. Let’s give it a try anyway.

Light the lamp!

OK, it’s heating it up nicely.

A couple minutes later:

The copper sulfate is turning whiter, but still, all of it still remains solid.

But look. There’s…
