Plz find this 13. How will you distinguish lead carbonate and zinc carbonate in solution ? What is observed when hot concentrated caustic s«ia solution is added to (a) Zinc and (b) Aluminium Write balanced equations.

Dear Student,

a) Zinc react with hot conc. caustic soda or hot conc. sodium hydroxide to produce zincate sodium and hydrogen.


b) Aluminum react with sodium hydroxide to produce sodium aluminate, hydrogen and sodium oxide.
2Al + 6NaOH «→» 2NaAlO2 + 3H2 + 2Na2O

for remaining query please ask in separate thread.
