| What mercury can combine with | ||||||||
| Mercury metal reacts in air at about 350 degrees Celsius to form mercury 2 oxide Mercury does not react with water under normal conditions. Mercury combines with flourine, chlorine, bromine, and iodine to create mercury 2 flouride, mercury 2 chloride, mercury 2 bromide and mercury 2 iodine Mercury does not react with non oxidizing acids but does react with concentrated nitric acid or concentrated sulphuric acid, and mercury slowly dissolves in diluted nitric acid to form mercurous nitrate. Mercury doesn't react with alkalis metals under normal conditions, |

| What these combinations are used for? | ||||||||
| Some of the other elements that mercury forms with to create new products are very useful. Mercuric chloride (HgCl2) is a very poisonous salt and was once used to disinfect wounds. Mercurous chloride(Hg2Cl2) also called calomel, is an antiseptic used to kill bacteria. Mercuric Sulfide (HgS) is used to make a red paint pigment called vermillon. Mercuric oxide (HgO) is used to make Mercury batteries. | ||||||||
