What is observed when copper oxide is added into excess dilute sulphuric acid?
Copper sulphate + water
What happens when dilute sulphuric acid is added to copper oxide?
CuO + H2SO4 -> CuSO4 + H2O copper sulfate and water produced
When dilute sulphuric acid is added to zinc granules the gas produced is?
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
Can copper sulphate be prepared from copper metal and dilute sulphuric acid?
No, it cannot be prepared by this method under normal conditions. For preparing copper sulphate, copper should be added to the sulphate salt of a metal which is less reactive than copper like Mercury, silver and gold
What chemical should be added to copper carbonate to make copper sulphate?
Sulphuric acid, because "sulphuric" is what gives copper sulphate it's name
What is the reaction between copper and sulfuric acid?
No, there is no reaction between copper & H2SO4 because according to reactivity series of metal hydrogen is more reactive than copper. Hence copper does not displace hydrogen from sulphuric acid..
What do you observe if dilute hydrochloric acid is added to the mixture of iron and sulphur?
ironchloride and sulphuric acid
What acid is formed when SO3 is added to water?
sulphuric acid
Chemical equation for iron added to dilute sulfuric acid?
Iron + sulphuric acid ----> iron sulphate + hydrogen
What is the precipitate of dilute sulfuric acid added to copper 2 carbonate?
they have sex with you
What happens when dilute sulphuric acid is added to zinc granules . Is it an exothermic or an endothermic reaction?
The reactions between metals and acids are always endothermic.
What happens when ammonia is added to copper sulfate?
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
