Question
Give an example to show the effect of concentration of nitric acid on the formation of oxidation product.
Advertisements
Solution
When nitric acid is mixed with copper metal, it produces distinct oxidation products.
\[\ce{3Cu + 8HNO3 (dil) -> 3Cu(NO3)2 + 2NO + 4H2O}\]
\[\ce{Cu + 4HNO3 (Conc) -> 3Cu(NO3)2 + 2NO2 + 2H2O}\]
