Question

It is possible that one of these might not be able to be a reaction!

1. A piece of solid Sn metal is put into an aqueous solution of Mg(NO3)2. Write the net ionic equation for any single-replacement redox reaction noting (l) (g) (aq) etc

2. A piece of solid Ni metal is put into an aqueous solution of Pb(NO3)2. Write the net ionic equation for any single-replacement redox reaction noting (l) (g) (aq) etc

3. A piece of solid Fe metal is put into an aqueous solution of HCl. Write the net ionic equation for any single-replacement redox reaction noting (l) (g) (aq) etc

Explanation / Answer

1) No reaction takes place

2) Ni (s) + Pb+2 (aq) ----> Ni+2 (aq) + Pb(s)

3) net ionic equation :

Fe (s) + 2H+ (aq) ---> Fe+2 (aq) ) + H2 (g)
