Question

In which of the following solution metallic ion can be displaced by aluminium : (i)CuSO4(ii)NaCL(CaCl2(IV)MgSO4 ?

Answer 1

Hey mate!!!

The ions present in solutions are

Cu2+,Na+,Ca2+,Mg2+

The metal dipped in solutions is

Al

As per the electrochmical series the order of reducing strength of metal is

Ca>Na>Mg>Al>Cu

So Al can only reduce

Cu2+

ion from its solution.i.e. Cu only will be displaced from

CuSO4

solution when Al metal is dipped in it.

Hope it helps you.

Answer 2

CuSO4. Bc Cu is the only metal in the options that lies below Al in the electrochemical series.
