Question

Which of the following pairs will give displacement reactions ?
(a) NaCl solution and copper metal.
(b) MgCl2 solution and aluminium metal.
(c) FeSO4 solution and silver metal.
(d) AgNO3 solution and copper metal.

Answer 1

$option \: d$

Answer 2

Answer:

According to the reactivity series of metals, copper metal is less reactive than sodium metal. Hence, no displacement reaction will occur between NaCl solution and copper metal. Again, aluminium metal is less reactive than Mg, so no displacement reaction will occur between MgCl₂ solution and aluminium metal
