Concentrated Nitric acid is a corrosive acid and a powerful oxidizing agent.
Conc. Nitric acid reacts with proteins to form a yellow coloured product. 
When conc. nitric acid comes in contact with our skin, it reacts with the proteins present in our skin i.e., keratin and forms a yellow coloured product called xanthoproteic acid.
