How will you prepare nitric acid? – InterviewSolution

1.	How will you prepare nitric acid?
Answer» Solution :Nitric acid prepared by heating EQUAL AMOUNTS of POTASSIUM or sodium nitrate with CONCENTRATED sulphuric acid. `KNO_(3)+H_(2)SO_(4)rarrKHSO_(4)+HNO_(3)` The temperature is kept as low as possible to avoid decomposition of nitric acid. The acid condennses to a fuming liquids which is coloured brown by the presence of a little nitrogen dioxide which is formed DUE to the decomposition of nitric acid. `4HNO_(3)rarr 4NO_(2)+2H_(2)O+O_(2)`
