what happens when zinc granules are treated with diluted solution of h2so4 , naoh , hcl , hno3
Answers
Metal +Acid= Salt + Hydrogen
-------------------------------------------
When zinc granules are treated with dilute solution of H2SO4 , we get Zinc Sulphate and H2 gas
Zn + H2SO4 ---> ZnSO4 +H2
----------------------------------------
When zinc granules are treated with dil.HCl, we get Zinc chloride and H2 gas
Zn +2 HCL- ---> ZnCl2 + H2
--------------------------------- ------------
Zinc reacts with dil.nitric acid to produce zinc nitrate and Hydrogen
Zn +2 HNO3 -----> Zn(NO3)2 + H2
--------------------------------------------------
Zn + NaCl ---> No reaction.
As Zinc is less reactive than sodium.Hence it cannot replace sodium from its salt.
--------------------------------------------------
Base + Metal ----> Salt + Hydrogen.
Zinc reacts with sodium hydroxide and forms sodium zincate and Hydrogen.
2NaOH + Zn -----> Na2ZnO2 + H2
