Nitric acid is a clear, colorless to brown, odorless liquid that is very toxic by inhalation and corrosive to metals or tissue. It accelerates the burning of combustible material and may cause ignition of combustible materials upon contact. Nitric acid is also reactive with strong acids such as hydrochloric, sulfuric, and nitric acids.
Sulfuric acid is a clear, colorless to brown, odorless liquid that is a strong inorganic acid and is very corrosive. It reacts violently with alcohol and water to release heat and will also react violently or explosively with organic materials, combustibles, strong bases such as sodium hydroxide and potassium hydroxide, reducing agents such as lithium, sodium, aluminum and their hydrates, and oxidizing agents such as perchlorates, peroxides, permanganates, chlorates, nitrates, chlorine, bromine, and fluorine. Sulfuric acid also reacts with most metals to produce flammable and explosive hydrogen gas.
Azotic acid is another name for nitric acid.
In summary, nitric acid and sulfuric acid are strong inorganic acids that are highly corrosive and reactive with other substances. Azotic acid is another name for nitric acid.
