1.	Give an example to show the effect of conecntration of nitric onthe formation of oxidation product.
Answer» Solution :DEPENDING upon the CONCENTRATION, `HNO_(3)` reacts with METALS to give different OXIDATION products. With dil. `HNO_(3),NO` is formed while with conc. `HNO_(3),NO_(2)` is formed. For example, `3Cu+8HNO_(3)(DILL.)to3Cu(NO_(3))_(2)+2NO+4H_(2)O` `Cu+4HNO_(3)(conc. )toCu(NO_(3))_(2)toCu(NO_(3))_(2)+2NO_(2)+2H_(2)O`
