What happens when mercury reacts with Sulphuric acid?

Mercury does not react with most acids, although oxidizing acids such as concentrated sulfuric acid and nitric acid dissolve it to give sulfate, nitrate, and chloride salts. Mercury dissolves to form amalgams with gold, zinc, and many other metals.

Can HG react with H2SO4?

Hg + 2H2SO4 → HgSO4 + SO2 + H2O. Mercury react with sulfuric acid to produce mercury(II) sulfate, sulfur dioxide and water. The reaction takes place in a boiling solution, in the presence of nitric acid.

What does HgSO4 H2SO4 do?

What is the function of the reagent HgSO4 and dilute H2SO4? It is basically used to convert an Alkyne into a Ketone. The reaction is called Kucherov Reaction. The reaction can be understood by following mechanism.

Is HgSO4 an acid?

Mercury(II) sulfate, commonly called mercuric sulfate, is the chemical compound Hg S O4. It is an odorless solid that forms white granules or crystalline powder. In water, it separates into an insoluble sulfate with a yellow color and sulfuric acid.

Can mercury combine with oxygen?

Mercury does not combine with oxygen to produce mercury(II) oxide, HgO, at a useful rate until heated to the range of 300 to 350 °C (572 to 662 °F). At temperatures of about 400 °C (752 °F) and above, the reaction reverses with the compound decomposing into its elements.

What is the color of mercury element?

silver-white
Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature. It is used in older thermometers, fluorescent light bulbs and some electrical switches.

Does HG react with dilute nitric acid?

Mercury does not react with non-oxidizing acids but does react with concentrated nitric acid, HNO3, or concentrated sulphuric acid, H2SO4, to form mercury(II) compounds together with nitrogen or sulphur oxides. Mercury dissolves slowly in dilute nitric acid to form mercury(I) nitrate, mercurous nitrate, Hg2(NO3)2.

Does alkyne react with H2SO4?

Reaction: Hydration of Alkynes As with alkenes,hydration (addition of water) to alkynes requires a strong acid, usually sulfuric acid, and is facilitated by mercuric sulfate.

What is the name for HgSO4?

Mercuric sulfate
Mercuric sulfate | HgSO4 – PubChem.

Why does Hg2 2+ exist?

Thus, Hg+ ions exist as dimeric species, i.e., Hg2+2 . In contrast, the electronic configuration of Cu(I) ion, i.e., Cu+ is [Ar]3d10 . Therefore, it has no unpaired electrons to form dimeric species, i.e., Cu2+2 and hence it always exists as Cu+ ion.

What is oxidation No of Hg?

Oxidation state of Hg is +2.

What is the function of the reagent HgSO4?

It is basically used to convert an Alkyne into a Ketone. The reaction is called Kucherov Reaction. The reaction can be understood by following mechanism. Alkynes will have low rate of electrophillic addition than alkynes. The metal catalyst like HgSO4 or CdSO4 will act as promoter and enhance the rate of electrophillic additon.

What is the reaction of HC ≡ H2SO4 / HgSO4?

In the following reaction, HC ≡ CH +H2SO4/HgSO4 → X Product ‘X’ will not give (a) Tollen’s test (b) Victor meyer test (c) Iodoform test (d) Fehiing solution test carbonyl compounds

How is HgSO4 used in the Kucherov reaction?

Unlike ordinary hydrolysis where H+ is the electrophipe in Kucherov reaction HgSO4 is used which forms a 3 membered cyclic intermediate somewhat like in the diagram which gives a stable intermediate compound thus increses the rate of the reaction. It is used in hydration of organic compound .it add H20 molecule to unsaturated compound

Which is a better catalyst HgSO4 or CdSO4?

The reaction is called Kucherov Reaction. The reaction can be understood by following mechanism. Alkynes will have low rate of electrophillic addition than alkynes. The metal catalyst like HgSO4 or CdSO4 will act as promoter and enhance the rate of electrophillic additon.
