Sodium and Chlorine. Formation of Sodium Chloride: Molten sodium burns when it is put into a container of chlorine gas. In the reaction a sodium ion loses an electron to form a sodium cation and a chlorine atom simultaneously gains an electron to form a chloride anion.
Aluminum is a reactive metal (un-noble), which should have a low corrosion resistance according to thermodynamics. The high corrosion resistance found on aluminum nevertheless, is due to the presence of a thin, compact film of adherent aluminum oxide on the surface.
Copper sulfate waste: I normally send all my waste liquids to be disposed of by a disposal company. However, I am starting to process it, to reduce the waste. My question: Once the copper sulfate solution has been treated with Sodium Carbonate and the clear liquid is decanted, what do you do with the solid?
Engage Show students two demonstrations and have them look for evidence that a gas is produced in the chemical reactions. Tell students that you will show them video of two demonstrations where water vapor and oxygen gas are produced in the exact same chemical reaction.
