Generally, when metals are treated with mineral acids, hydrogen gas is liberated but when metals (except Mn and Mg) are treated with HNO_3, hydrogen is not liberated why? |
| Answer» Solution :It is because `HNO_3` is a strong oxidising agent. It oxidises the `H_2` PRODUCED to `H_2O` and it self get REDUCED to any of the oxides of the nitrogen LIKE `NO_2,NO` etc. | |
