Mercury(II) oxide, also called mercuric oxide, has a formula of HgO and a formula weight of 216.6. It has a reddish-orangy color. Mercury(II) oxide is a solid at room temperature and pressure.
Uses
HgO is sometimes used in the prodcution of mercury as it decomposes quite easily.
It is also used as a material for anodes for mercury batteries.
