Laboratory Use

Commercial grade, which your average quality, is usually comprised of nitric acid solutions that are between 52% and 68% nitric acid and the remaining part is water.

Laboratories need a higher grade and their concentrations are generally 70% to 99% nitric acid. When a solution is made up of more than 86% nitric acid, it is then referred to as a fuming nitric acid. When it reaches concentrations over 98% it can be broken down into two separate classifications; white fuming nitric acid or red fuming nitric acid.
