Question

Which of the following pairs will give displacement reactions?

(a) NaCl solution and copper metal

(b) MgCI2 solution and aluminium metal

(c) FeSO4 solution and silver metal

(d) AgNO3 solution and copper metal​

Answer 1

Answer:

(d) AgNO3 solution and copper metal.

Copper metal and silver nitrate solution gives displacement reaction and the chemical equation can be written as:

$Cu+2AgNo_3→cu(No_3)_2+2Ag$

Answer 2

Answer:

(b)Mgcl2 solution and aluminium metal
