What happens when H2SO4 reacts with sulphur?

The reaction between sulphur and conc. Sulphuric acid forms sulphur dioxide and water. By the change in the oxidation state, the oxidised and reduced species or oxidiser or reducer can be determined.

What is the product of the reaction H2SO4?

Carbon reacts with sulfuric acid to produce carbon dioxide and sulfur dioxide gas along with water. Sulfuric acid should be a concentrated, heated solution.

What happens when H2SO4 reacts with SO2?

Sulfuric acid exhibits a dramatic catalytic effect on the hydrolysis reaction of SO2 as it lowers the energy barrier by over 20 kcal/mol. The energy barriers for the three hydrolysis reactions are in the order SO2 + (H2SO4)-H2O > SO2 + (H2SO4)2-H2O > SO2 + H2SO4-H2O.

Why is conc H2SO4 not used to dry H2S?

Hydrogen sulphide gas cannot be dried using sulphuric acid as H2S gas is oxidised by sulphuric acid to Sulphur. Therefore, the H2S gas has chemical action with acid and hence it reacts with it , therefore, cannot be dried using it.

What is the difference between H2S and H2SO4?

The only difference between S-I and H2S cycle is that the H2SO4 decomposition reaction is replaced by a reaction between hydrogen sulfide and sulfuric acid which produces sulfur dioxide, elemental sulfur and water. The sulfuric acid concentrations were between 90 and 96 wt\%.

How H2SO4 is formed?

Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process.

Which of following gases can be dried by conc H2SO4?

Hydrogen is dried by passing it through conc H2​SO4​

What does H2S react with?

Hydrogen sulfide reacts with metal ions to form metal sulfides, which are insoluble, often dark colored solids. Lead(II) acetate paper is used to detect hydrogen sulfide because it readily converts to lead(II) sulfide, which is black.

What happens when cu reacts with H2SO4?

What happens when Cu reacts with H2SO4? So copper does not react with dilute sulphuric acid but reacts with concentrated sulphuric acid. When copper is heated with concentrated sulphuric acid. When copper reacts with concentrated sulphuric acid sulphur dioxide is produced by the reduction of H2SO4.

What happens when ethyl alcohol is heated with conc H2SO4?

When ethyl alcohol is heated with conc. H2SO4 , the product obtained is? , the product obtained is? When excess ethanol is heated with sulphuric acid, we get Diethyl ether. But when excess Sulphuric acid is used, it behaves like a dehydrating agent and we get Ethene.

What is the product formed when acetone reacts with H2SO4?

H2SO4 is a catalyst for aldol reactions, including that of acetone with itself. I do have the following to add, however. (The second of these has the trivial name mesityl oxide). From these + acetone + themselves, you get a plethora of further products, including mesitylene which Vishal mentioned.

What is the chemical name of H2SO4?

H2O is that about which we should be careful enough. It is the formula of water which we use in all sectors of our daily life. H2SO4 is sulphuric acid. It is a powerful mineral acid and oxy-acid. Its basicity is 2. Its molecular weight is 98 g mol-¹ and equivalent weight is 49 g equivalent-¹ .
