Details

Nitric Acid 40% Solution, Lab Grade

Nitric Acid (HNO3) is a corrosive mineral acid commonly known as aqua fortis (Latin for "strong water") and the spirit of niter. The pure chemical is colorless at room temperature but breaks down into nitrogen oxides and water leading to a yellowish tinge of older samples. Our Nitric Acid, Lab Grade contains 40% pure Nitric Acid in its solution with water and is reasonably pure in terms of heavy metal impurities.

Nitric acid is a versatile chemical and is used in various laboratory processes, including:

Acid Digestion: It is used to digest samples for elemental analysis by techniques such as inductively coupled plasma (ICP) or atomic absorption spectroscopy.

Metal etching: Nitric acid is used for etching metals in laboratory settings.

Nitrations: It is involved in various chemical reactions, such as nitrations, where organic compounds are reacted with nitric acid to introduce nitro functional groups.

Cleaning: Nitric acid can be used to clean laboratory glassware and equipment.
