Explain the following:
Dilute nitric acid is generally considered a typical acid but not so in its reaction with metals.
उत्तर
Dilute nitric acid is generally considered a typical acid but not in its reaction with metals because the action of nitric acid on metals depends on the temperature and concentration of nitric acid. These conditions are not required in case of hydrochloric acid or sulphuric acid
