What else can I help you with?
What two colour changes do you get when you add copper sulphate solution to iron wool?
When you add copper sulphate solution to iron wool. The iron wool turns copper in color and the copper sulphate solution turns pale blue as the iron displaces the copper from the copper sulphate solution forming iron sulfate.
Why do you add hydrochloric acid to test for sulphate?
Hydrochloric acid is added to a solution being tested for sulphate ions to precipitate the sulphate as barium sulphate. This is a confirmatory test for the presence of sulphate ions in the solution because barium sulphate is insoluble and forms a white precipitate.
How do you test for sulphate ions?
add barium chloride or barium nitrate to a solution containing sulphate ions SO4 2-. To the same solution add hydrochloric acid in excess. OBSERVATIONS, a white precipitate which is insoluble in excess acid confirms presence of SO42- IF IT DISSOLVES then it confirms SO32- ----------------------------------------- 1) Add barium nitrate solution under acidic conditions (use an equal volume of hydrochloric acid) to the unknown solution 2) A white precipitate of barium sulphate forms if sulphate ions are present
What do you get when you add iron filings to nitric acid?
When you add iron filings to nitric acid, you will observe a chemical reaction where the iron reacts with the nitric acid to produce iron nitrate and release nitrogen dioxide gas. It's a redox reaction in which the iron is oxidized and the nitric acid is reduced.
What happens when you add iron powder to hydrochloric acid?
When iron powder is added to hydrochloric acid, a chemical reaction takes place which produces hydrogen gas and iron(II) chloride. The iron powder dissolves in the acid and the hydrogen gas is released as bubbles. The iron chloride formed remains in solution.

Zinc sulphate can be made in a reaction between and an acid give the name of the acid?
zinc sulphate is made of a reaction between zinc and what acid

What to add to beryllium to get beryllium sulphate?
sulphur is added to beryllium to get beryllium sulphate
What is made when you add zinc to sulfric acid?
Zn + H2SO4 --> ZnSO4 + H2 Zinc sulphate and hydrogen gas are produced.
What is added to sodium hydroxide that will get sodium sulphate and water?
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
Ho do you dissolve Iron SULFATE?
Iron forms two types of sulfates, Ferrous sulfate FeSO4 and Ferric sulfate Fe2(SO4)3 , Ferrous sulfate is easily soluble in normal water and Ferric sulfate may be dissolved in water by adding a little amount of sulpuric acid.
What do you get when you add iron filings to nitric acid?
When you add iron filings to nitric acid, you will observe a chemical reaction where the iron reacts with the nitric acid to produce iron nitrate and release nitrogen dioxide gas. It's a redox reaction in which the iron is oxidized and the nitric acid is reduced.
What happens when you add iron sulphide to acid?
I goes all gloppy and odd
Which chemical is used for the detection of sulphate in aqueous solution?
Add some barium chloride solution to the neutral or weakly acid sulfate solution
What happens when you add iron powder to hydrochloric acid?
When iron powder is added to hydrochloric acid, a chemical reaction takes place which produces hydrogen gas and iron(II) chloride. The iron powder dissolves in the acid and the hydrogen gas is released as bubbles. The iron chloride formed remains in solution.
