CaCl 2 is an ionic compound with chemical name Calcium Chloride. It is also called Calcium chloride anhydrous or Calcium dichloride. It is an ionic compound of chlorine and calcium. At room temperature, it is a crystalline solid white in colour. It is highly soluble in water and hence is hygroscopic in nature.
2009/11/1· Look at the compounds we tested and explain how we can be sure that it is the metal atoms that are responsible for the colours that you see. We can know for certain that it’s the metal that causes the colour because they have polar covalent bonds so the electrons are more around the metal than the non-metal so they release the colour based on the energy of the metal because that is where the …
