What is the action of Cone. `HNO_(3)` and dil `HNO_(3)` on zinc metal.

Text Solution

Verified by Experts

Conc.`HNO_(3)` Oxidises zinc to zinc nitrate and itself reduces to `NO_(2)`
`Zn+4NHO_(3)rarrZn(NO_(3))_(2)+2H_(2)O+2NO_(2)`
Dilute nitric acid oxidises zinc to zinc nitrate and itself reduces to `N_(2)O`
`4Zn+10HNO_(3)rarr4Zn(NO_(3))_(2)+5H_(2)O+N_(2)O`
