Question

An excess of iron fillings is added to a solution
containing a mixture of the ions
Mg2+, Ca2+, Cut, Ag!
Which two metals will be displaced from this
solution?
5
O Calcium and Copper
0Calcium and Magnesium
O Copper and Silver
O Magnesium and Silver​

Answer 1

The two metals that will be displaced from this  solution are:

(c) Copper and Silver

- The metal which is placed above will displace the metal which is placed below it in the reactivity series of metals.

- The order of the given metals in reactivity series is:

Calcium > Magnesium > Iron > Copper > Silver​

- So, Iron fillings will not displace Calcium and Magnesium.

- They will only displace Copper and Silver from the solution.
