Which of the following combination(s) of compounds undergo displacement reaction?
and NaCl solution
solution and silver metal
solution and copper metalOpen in App
Solution
The correct options are
C solution and silver metal
D solution and copper metal
If the metal is more reactive than the metal ion of the salt then the reaction occurs otherwise the salt solution and the metal remains unreacted.
If we look at the pairs of metal salt and the metal then silver nitrate and copper metal undergo displacement reaction as copper is more reactive than silver. Hence it displaces silver to form copper nitrate.
Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) + 2Ag(s)
Similarly, ferrous sulphate solution and aluminium metal will also undergo displacement reaction as aluminium is more reactive than iron.
3FeSO4(aq) + 2Al(s) → Al2(SO4)3(aq) + 3Fe(s)
