Question

2. Test tubes A, B and C contain zinc sulphate, silver nitrate and iron (II) sulphate solutions respectively as shown in the figure. Copper pieces are added to each test tubes. Blue colour will appear in case of Copeer pices (a) Test tube A (b) Test tube B (c) Test tube C (d) All the test tube What is are the for ionic compounds?​

Answer 1

Explanation:

No reaction takes place in case of test tube A and C becoz iron and zinc is highly reactive that copper

in case of silver nitrate solution blue colour of copper is appear because copper is more reactive than silver .

Answer 2

Answer:

(b) Test Tube B

Explanation:

A=ZnSO 4

B=AgNO 3

C=FeSO 4

• When copper pieces added in each beaker, only less reactive solution will be displaced by Cu.
• According to reactivity series Cu is more reactive than silver and less reactive than Zn and Fe.

Hope this helps!!
