Copper(I) Oxide or Cuprous Oxide is the inorganic compound with the formula Cu2O. It is one of the principal oxides of copper. This red-coloured solid is a component of some antifouling paints. The compound can appear either yellow or red, depending on the size of the particles. Copper(I) oxide is found as the reddish mineral cuprite.
Property: Red powder with density 6.00, melting point 1235°C., boiling point 1800°C, it dissolves in hydrochloric aid, ammonium chloride and ammonia water, it doesn't dissolve in alcohol or water. Cuprous Oxide can be slowly turned into copper oxide in wet weather, and it is very steady and poison in dry weather.
