What would happen if you reacted copper with dilute hydrochloric acid?
Probably nothing: Hydrogen is higher than copper in the electromotive series, so that copper can not displace hydrogen from its compounds,
Does dilute Hydrochloric acid dissolve Copper?
No, because copper is below Hydrogen in the activity series list, (meaning the presence of hydrogen is not enough to replace copper) there is no reaction that takes place.
Why does copper not evolve hydrogen on reacting with dilute sulphuric acid?
Standard reduction potential ( SRP) of copper is more ( + 0.34 v ) than that of Hydrogen ( 0.00 v )
Why does copper not liberate hydrogen on reacting with dilute sulphuric acid?
it is because hydrogen gas usually liberates when an acid reacts with metal
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..
Can copper be used be to prepare hydrogen by reaction with dilute acids?
No, this would not be a good way. Copper is very unreactive towards dilute acids.
Does copper react with dilute sulfuric acid?
No, as copper is below Hydrogen in the reactivity series

How do acids react with dilute acid?
metals reacts with dil.acid to form metal salt and hydrogen gas releases . eg - copper + dil. sulphuric acid = copper sulphate + hydrogen gas
Why is the reaction between potassium and dilute acids not used to prepare hydrogen in the laboratory?
Because they have a more efficient way of doing it.
What is formed when copper is added to dilute sulphuric acid?
cu + H2so4 --->cuso4+2H two molecules of hydrogen evolves........
What happens when dilute hydrochloric acid is added to copper turnings?
Copper turnings react with HCl to form Copper chloride and give out hydrogen gas. Cu(s) + 2HCl -----> CuCl2 +H2(g)
What happens when copper is reacted with dilute sulfuric acid?
Copper does not react with dilute Sulphuric acid.
