This is an interesting reaction but what does it mean? What does this reaction mean? How can we explain it? Let’s first look at the chemical structure of sodium metal. Sodium is an element with oxidation state 0 and the reaction takes place between sodium and chlorine gas, which is pure. While sodium is an electron donor, chlorine is an electron acceptor. During the reaction, sodium loses one electron and chloride gains one.
The reaction between copper and aluminum produces the compound copper II sulfate. Copper reacts with aluminum to produce different types of ions depending on its oxidation status. It loses one electron or two and gains another. This is called an oxidation/reduction react and copper metal is created, while aluminum disappears. This is a fascinating reaction that you can learn more about in chemistry class, or online.
