Dragonium (Dr) is an element only found in the scales of dragons. It is known to exist only in the oxidation state of +3, and it is a metal. After dragons go for their morning swim in the Pacific Ocean, their scales change color due to the formation of a chlorine salt of dragonium which crystallizes out with four water molecules per each dragonium atom. Select the name of this compound.
