What happens to nitric acid when exposed to sunlight?

Exposure to light causes the formation of nitrogen dioxide, which gives the liquid a yellow color. Concentrated nitric acid containing dissolved nitrogen dioxide is termed fuming nitric acid, which evolves suffocating, poisonous fumes of nitrogen dioxide and nitrogen tetroxide (O’Neil et al.

Can nitric acid burn your skin?

Dermal exposures: Nitric acid is corrosive to the skin, producing severe burns, ulceration, scarring, dermatitis and yellow staining of the skin.

Why do nitric acid stain the human skin yellow?

These yellow stains turn orange when neutralized. Systemic effects are unlikely, however, and the substance is not considered a carcinogen or mutagen.

What happens when nitric acid falls on the skin?

Nitric acid vapor is a strong irritant at lower concentrations and can cause conjunctivitis and even necrosis of the conjunctiva. Dermal exposures: Nitric acid is corrosive to the skin, producing severe burns, ulceration, scarring, dermatitis and yellow staining of the skin.
