Question

Which of the following undergo chemical
reactions? Describe the reactions and write
their equation.
(i) iron and copper sulphate
(ii) copper and ferrous sulphate
(iii) magnesium and zinc sulphate
(iv) zinc and magnesium sulphate​

Answer 1

Answer:

CuSO4 + Fe can undergo a chemical reaction. As iron metal is more reactive than copper metal, iron displaces copper from copper sulphate solution and forms aqueous iron sulphate (FeSO4) and solid copper (Cu).

Answer 2

Answer:

A】iron and copper sulphate

fe+cuso4 ---------- feso4+cu {colour change take place,displacement reaction}.

B】copper and ferrous sulphate

no reaction takes place since copper is less reactive.

C】magnesium and zinc sulphate

zn+mgso4 -----------znso4+mg {displacement reaction}

D】zinc and magnesium sulphate

no reaction takes place since zinc is less reactive.
