Melting #2: Copper (II) Sulfate (Didn’t Work)

Melting #2: Copper (II) Sulfate (Didn't Work) 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 …

Melting #1: Sulfur (Making a Sulfur Coin)

Melting #1: Sulfur (Making a Sulfur Coin) I'm going to be melting sulfur... Sulfur is a chemical element with symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow crystalline solid at room temperature. Sulfur Melting Point: 115 °C ( 239.38 °F) Yay! the sulfur is melting! …
