Question

which of the following pairs will give displacement reactions?
a) NaCl solution and copper metal
b) MgCI^ solution and aluminum metal
c) FeSO^ solution and silver metal
d) AgNO^ solution and copper metal​

Answer 1

Answer:

(d)

Explanation:

Since copper is more reactive than silver so it will displace silver from silver nitrate

Answer 2

Answer:

d) AgNO^ solution and copper metal

AGNo 3 Solution & copper metal

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

$Cu+2AgNo_3→cu(No_3)_2+2Ag$
