Question

on adding zinc granules to freshly prepared ferrous sulphate solution a student observes that​

Answer 1

Answer:

When zinc is introduced to an iron sulphate solution, the colour of the iron sulphate solution changes. Since zinc is more reactive than iron, it displaces iron from its iron sulphate solution, resulting in a grey precipitate of iron and a colourless zinc sulphate solution.

Answer 2

☘️ Answer:

The student observed that, colour of the solution changes from green to colourless when zinc is added to iron sulphate solution because zinc is more reactive than ferrous. Therefore, displaces ferrous sulphate solution and forms in sulphate solution.

The chemical equation is given below:

$\tt \: Zn(s) + FeSO_4(aq) → ZnSO_4(aq) + Fe(s)$
