nitric acid >55-56%

Nitric acid is a colorless to yellow or red liquid sometimes fuming reddish brown vapors with a suffocating odor. Nitric acid is soluble in water with release of heat. Nitric acid is corrosive to metals or tissue. Nitric acid will accelerate the burning of combustible materials and Nitric acid may even cause ignition upon contact with combustible material. Nitric acid is fully soluble in water and may react violently upon contact with water with the evolution of heat, fumes and spattering. Prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects
