What is mercury sulfate used for?
Mercury(II) sulfate is used for gold and silver extraction, and to make other mercury compounds. Used as catalyst in the conversion of acetylene to acetaldehyde and used as a electrolyte in primary battery. It is commonly used as a catalyst in oxymercuration-demercuration, a type of electrophilic addition reaction.

Is mercuric sulphate soluble?
Mercurous sulfate is a white to yellow crystalline powder. Soluble in hot sulfuric acid, dilute nitric acid.
Is mercury sulfate insoluble in water?
soluble in dilute nitric acid, Insoluble in water, Soluble in hot sulfuric acid. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
Is HgS soluble in water?
Mercury sulfide, or mercury(II) sulfide is a chemical compound composed of the chemical elements mercury and sulfur. It is represented by the chemical formula HgS. It is virtually insoluble in water.
What is the role of hgso4?
It is used as reagent in hydration of alkyne. This reagent favors formation of aldehydes & ketones via enol tautomerisation. in other words, it favours addition of 1 molecule of water on triple bond according to markonikov rule without rearrangement.
Does hgcl2 dissolve in water?
Water-soluble, it is highly toxic.
What is HgS used for?
mercury compounds Mercury(II) sulfide, HgS, is a black or red crystalline solid used chiefly as a pigment in paints, rubber, and plastics.
Why are HgS insoluble in water?
Calcium compounds are more or less water-soluble. When compounds are insoluble in water, the general reason is that the bonding within that species is stronger than the bonding between it and water.
Why mercuric sulphate is used in hydration of alkynes?
Mercury(II)-Catalyzed Hydration of Alkynes As with alkenes, hydration (addition of water) of alkynes requires a strong acid, usually sulfuric acid, and is facilitated by the mercuric ion (Hg2+). However, the hydration of alkynes gives ketone products while the hydration of alkenes gives alcohol products.
What is the function of HgCl2?
Used in photography, disinfectants, wood preservatives, fungicides. Mercury chloride (HgCl2) is a highly toxic compound that volatizes slightly at ordinary temperature and appreciably at 100 degrees C. It is corrosive to mucous membranes and used as a topical antiseptic and disinfectant.
