Why does your skin turns yellow when nitric acid falls on skin ?
Asked by Madhurima | 03 Dec, 2013, 03:16: PM
answered-by-expert Expert Answer
Proteins and amino acids that contain phenyl rings form a yellow colored compound when treated with concentrated nitric acid. The yellow stains on the skin are caused due to the reaction of nitric acid with protein keratin present in the skin. This reaction is called xanthoproteic reaction.
