 ===== Copper Sulfate =====
@@ Line 15: / Line 14: @@
 The first crystals, that we are growing are copper sulfate crystals. They give an intense blue color and are quite easy to grow. For this, we need to acquire [[https://www.laborladen.de/Kupfersulfat-Pentahydrat-fein-KupferII-sulfat-CuSO4|Copper(II)-sulfate pentahydrate]]. The chemical formula is: $\ce{ CuSO4 * 5 H2O }$

 Begin with boiling about 800ml of water. When it is boiling, transfer it to the beaker and start adding Copper(II)-sulfate pentahydrate until nothing will dissolve anymore. It should have a deep blue color, see picture 1.2.
