Why do you add hydrochloric acid to test for sulphate?
you do it for cabonates
What happens when you add iron to copper sulphate?
1. Iron sulfate is formed. 2. The released copper is deposited on the surface of the iron piece.
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 will be the observation when you will add aqueous sodium hydroxide is added to aqueous iron 3 sulphate?
Green Percipitate

How much sulphuric acid do you need to make copper sulphate?
you can add as much as you want as long as you add enough copper oxide. Hope this Helped you! :-)
What acid makes magnesium sulphate?
Magnesium sulfate may be derived from sulfuric acid.
What is made when you add zinc to sulfric acid?
Zn + H2SO4 --> ZnSO4 + H2 Zinc sulphate and hydrogen gas are produced.
