What is the equation for copper reaction wid dil. sulphuric acid???

Question

plzzzz........ telll me

Answer 1

Cu + H2S, H2CO3

Answer 2

Cu + H2SO4 -> CuSO4 + H2

This is the general reaction of all metals with strong acids. The product is a solution of the metal salt and hydrogen gas. The "achedemic" form of the equation is:

Cu(s) + H2SO4(l) -> CuSO4(aq) + H2(g)

Answer 3

Copper does not react with dil. H2SO4. [as copper is very less reactive]

But it may react with conc. H2SO4

The reaction will be

Cu + H2SO4 -------> CuSO4 + H2

i.e

Copper  +  Sulphuric Acid -------> Copper Sulphate  +  Hydrogen

Important Information : You can find the reaction of any acid on any metal. If you ignore the diluteness (as you need to do practicals to find it) you can form any reaction.

Consider that any metal ' X ' reacts with any acid HABC (where H is hydrogen as its presence is must in an acid, and A,B and C can be any other elements. Not necessary that exactly 3 present. it can be more or less.)

then the reaction will follow

X + HABC ----> XABC + H

ie metal replace H from the acid and takes its place.

Answer 4

Copper metal may not react with dilute sulphuric acid in absence of oxygen (air) or some other oxidising agents like nitric acid.

In presence of air or oxidising agent the product is copper sulphate.

  Cu + H2SO4  + [O]  -------------> CuSO4 + H2O

Answer 5

The above reaction is not possible
