Answer 1

Answer:

Explanation:

Four metals A, B, C and D are in turn added to the following solutions one by one. The observations made are tabulated below.

Metal Iron (II) sulphate Copper (II) sulphate Zinc sulphate Silver nitrate

A No reaction Displacement        -       -

B Displacement           - No reaction       -

C No reaction  No reaction No reaction Displacement

D No reaction No reaction No reaction No reaction

Answer the following based on the above information :

(i) Which is the most reactive metal? Why?

(ii) What would be observed, if 'B' is added to a solution of Copper (II) sulphate and why?

(iii) Arrange the metals A, B, C and D in order of increasing reactivity.

(iv) Which one among A, B, C and D metals can be used to make containers that can be used to store any of the above solutions safely?
