Question

What type of reaction is copper oxide + sulphuric acid? What are the products?

Answer 1

`CuO(s) + H_2SO_4(aq) rarr CuSO_4(aq) + 2H_2O(l)`

Explanation:

This is simply an acid-base reaction... And it is good to do because `CuSO_4(aq)` forms a lovely, blue-coloured solution due to the formation of `[Cu{(OH)_2}_6]^(2+)`...i.e.

`underbrace(CuO(s))_"black salt"stackrel(H_2SO_4)rarrunderbrace(CuSO_4(aq))_"blue solution" + H_2O(l)`
