About 90% of nitric acid is manufactured by Ostwald's process
It is a strong mono basic acid which reacts with almost all the metals except noble metals
Yellow color of impure nitric acid is because of dissolved oxides of nitrogen (mainly NO2)
Arc process of nitric acid manufacture is economical as compared to Ostwald's process
