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.
