Nitric Acid

HNO3: A strong acid, it is toxic and can cause severe burns. Transparent colorless or yellowish, fuming, suffocating, caustic and corrosive liquid. Nitric acid boiling point is 83C. A 70 percent solution is used in the S.S.E. laboratory for junction depth measurements. Nitric acid is also present in the metal etch solution used for the Aluminum etch procedure.

Can water burn?

It’s known that water consists of atoms of molecules of oxygen and hydrogen. Since any compound with oxygen indicates the ability of the substance to burn, water is no exception. Thus, water has a surprising property of already "burnt out" compound.

Semipermable Membrane
