Hydrated compound

The video tutorial explains the concept of hydrated salts, focusing on copper sulfate, which contains water molecules within its crystal structure. When heated, the water is released, changing the salt's appearance from blue to white, a process that can be reversed by adding water. The video also highlights the giant gypsum crystals found in Mexico's Naika caves, which are composed of calcium, sulfur, and oxygen.
