Saturate dilute hydrocyanic acid with mercuric oxide; evaporate and crystallise.
Mercuric Salts, a bright yellow precipitate of mercuric oxide.
mercuric oxide can be obtained either as a brick-red or as a yellow substance.
Redissolve the precipitate in nitric acid, and boil the solution with mercuric oxide, which does not precipitate the ferric oxide.
This is obtained by solution of mercuric oxide, in excess of nitric acid.
Various oxychlorides are formed by digesting corrosive sublimate with mercuric oxide.
The molecule of mercuric oxide and the atom of oxygen which it contains have the ratio 216: 16.
In a former chapter it was shown that mercuric oxide decomposes when heated to form mercury and oxygen.
Substances which burn with difficulty may be mixed with mercuric oxide in addition to copper oxide.
Again, suppose we wish to find what weight of oxygen can be obtained from 15 g. of mercuric oxide.
