It is due to nitric dioxide gas contamination. Very pure nitric acid is clear because the synthesis of it removes it of nitric dioxide.

In this reaction the yellow xanthoproteic acid is formed.

The nitric acid used in laboratory is colorless. The very concentated nitric acid - the fumans acid - with dissolved nitrogen oxides, can release white, red or brown fumes, very corrosive and toxic.

Referring to the coloured bands... Red touches yellow - kill a fellow. Red touches black - venom lack. The order of the bands on a Coral snake is red, yellow, black, yellow. With the harmless king snake it's red, black, yellow, black.

Actually you have it backwards. It goes: If red touches yellow you're a dead fellow, if red touches black, you're OK jack.
The yellow part is called the yolk, and if fertilized develops into the embryo.

What does a yellow line in the eyes indicate.
"Red and yellow kill a fellow, red and black you'll make it back."That is the most common form of the phrase. Please keep in mind that it only applies to snakes in the United States. If you travel to Mexico, or countries in Central or South America, this rule does NOT apply.Red touches yellow - kill a fellow. Red touches black - venom lack.
a xanthoprotein is a nitroprotein. The xanthoprotein test is characterisitic reaction of proteins that contain phenyl aromatic function. Nitric acid react with this phenyl group to yellow colored aromatic compound. The yellow stains on the skin from nitric acid exposure is the result of xanthoprotein.
