What happens when ferrous sulphate react with nitric acid?

Complete answer: The brown ring test is used to detect the presence of nitrate ions. This is done by addition of Ferrous sulphate to nitric acid solution. This Fe+3 reacts with the sulphate ions to form Fe2(SO4)3which is a brown colour solid formed.

What happens when nitric acid reacts with Sulphuric acid?

Sulphuric acid(H2SO4), NO2 and water are formed when concentrated nitric acid reacts with sulphur.

What happens when ferrous sulphate is added to the mixture of conc nitric acid and conc Sulphuric acid?

Ans- When FeSO4 is added to the well cooled mixture of dilute HNO3 and conc. H2SO4, it give brown ring of nitrous ferrous sulphate.

What do you observe when nitric oxide is passed through freshly prepared ferrous sulphate solution?

black colour solution
Nitric oxide gives a black colour solution when it is passed through ferrous sulphate solution because nitric oxide combines with ferrous sulphate to form a black coloured complex compound known as “Nitroso ferrous sulphate”.

What is the action of hot and concentrated sulphuric acid on ferrous sulphate?

When sulfuric acid reacts with iron it makes iron (II) sulfate which is a pale green color.

What is the mixture of nitric acid and sulphuric acid called *?

NITRATING ACID
NITRATING ACID, MIXTURE, (WITH <= 50\% NITRIC ACID) is a mixture of nitric with sulfuric acids. Reacts as a strong acid.

Which of the following is the ionic equation for the reaction between ferrous sulphide and sulphuric acid?

Fe+2H2SO4→2FeSO4+H2.

Why do we add sulphuric acid before adding water for dissolving ferrous sulphate?

Fe2+ and Al3+ ions undergo hydrolysis, therefore, while preparing aqueous solutions of ferrous sulphate and aluminium sulphate in water, 2-3 mL dilute sulphuric acid is added to prevent the hydrolysis of these salts.

What happens when freshly prepared ferrous sulphate?

A freshly prepared ferrous sulphate solution is used because on exposure to the atmosphere, it is oxidized to ferric sulphate which will not give the brown ring.

Why Sulphuric acid is added to ferrous solution?

The oxidation of ferrous sulfate with oxygen-sulfur dioxide mixtures in aqueous sulfuric acid has been investigated. In the presence of excess oxygen, sulfur dioxide produces fast oxidation of ferrous ion probably because of the formation of reactive radicals such as HSO3, HO2, and OH.

What happens when ferrous sulfate reacts with nitric acid?

The reaction is as follows. So, by adding nitric acid to an acidified solution of ferrous sulfate, the nitric acid will oxidize the iron (II) and convert it to iron (III). 8 clever moves when you have $1,000 in the bank.

What happens when sulfur reacts with hot concentrated sulphuric acid?

When sulfur reacts with hot concentrated, given products are little bit different from previous reaction. In this reaction, sulfur is oxidized to sulfuric acid (H 2 SO 4) while nitric acid is reduced to nitrogen dioxide. Therefore oxidation number of sulfur is changed from 0 to +6.

What is the oxidation number of sulfur in concentrated nitric acid?

Sulfur and concentrated nitric acid reaction Sulfur is oxidized to sulfur dioxide while nitric acid is reduced to nitrogen dioxide. S + HNO 3 → SO 2 + NO 2 + H 2 O Therefore oxidation number of sulfur is changed from 0 to +4.

Why is sulfuric acid added to iron before titration?

Why is sulfuric acid added to iron before titration? Sulphuric Acid (H2SO4) is used in the redox titration process because it provides the H (+) ions necessary for the reaction to occur more quickly whilst the sulphate (-) ions barely react during the reaction. Therefore, sulfuric acid is added to make the solution acidic.
