What is the word equation for mercury burning in air?
What is the word equation for mercury burning in air?
Reactions are usually described using chemical equations. Equations may be expressed in words: Mercury(II) oxide decomposes to mercury and oxygen. Using formulas, we state this reaction as: 2 HgO 2 Hg + O2.
What is the formula for mercury II sulfate?
HgSO4
How do you make mercuric sulfate?
Mercury sulfate, HgSO4, can be produced by heating concentrated H2SO4 with elemental mercury: Hg + 2 H2SO4 → HgSO4 + SO2 + 2 H2O. Or by dissolving solid yellow mercuric oxide in concentrated sulfuric acid and water.
What is mercury sulfate used for?
Mercuric sulfate appears as odorless white granules or crystalline powder. Denser than water. It is toxic by inhalation and by ingestion. It is used in medicine, for gold and silver extraction, and to make other mercury compounds.
What is the correct formula for mercury II bromide?

Is mercuric bromide soluble in water?
Mercuric bromide appears as white rhombic crystals. Sensitive to light. Slightly soluble in water and denser than water. Severely toxic by inhalation and ingestion.
Is HgSO4 soluble in water?
No, HgSO4 that is mercuric sulphate is NOT SOLUBLE in water. It is because when it is added in water, it forms an insoluble sulfate along with sulfuric acid. It is widely used as a catalyst in the hydration of alkynes as it doesn’t hydrolyze itself. It is very poisonous and must not be inhaled.
