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