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:

option A. iron is more reactive than Copper and Tin copper sulphate copper is replaced by iron and the product which is formed is iron sulphate and copper

Answer 2

Answer:

(i) iron and copper sulphate

  fe + cuso4 -------- feso4 + cu (colour change takes place, displacement reactio)

(ii) copper and ferrous sulphate

no reaction takes place since copper is less reactive

(iii) magnesium and zinc sulphate

zn + mgso4 -------- znso4 + mg (displacement reaction)

(iv) zinc and magnesium sulphate

no reaction takes place since zinc is less reactive.
