When zinc reacts with dilute nitric acid nitrous oxide is produced?
Hereof, what are the products formed when zinc reacts with dilute nitric acid?
The products formed when zinc reacts with dilute nitric acid are zinc nitrate and hydrogen gas; i.e. 3Zn + 7HNO3 ---> Zn(NO3)2 + NH2OH + 2H2O; HNO3 + 6H ---> NH2OH + 2H2O ; (Hydroxylamine.) HNO3 + 8H ---> NH3 + 3H2O ; (Ammonia.)
Likewise, when zinc reacts with very dilute hno3 the oxidation state of nitrogen changes from? Generally, when zinc reacts with nitric acid, it forms zinc nitrate. But when we take very dilute solution of nitric acid, if forms ammonium nitrate as well. So, here Nitrogen is reducing from +5 to +4.
Also, what happens when zinc reacts with nitric acid?
Zinc reacts with concentrated Nitric acid to produce Zinc nitrate, nitrogen dioxide and water.
Why zinc does not react with nitric acid?
Aluminum and zinc do not react with concentrated nitric acid since a thick, hard to dissolve oxidation layer builds (passive oxidation) that protects the metal against further assaults.
