Description
Nitric acid, diluted, heavy metal-free is a Reag. Ph. Eur. nitric acid reagent according to Chapter 4.1.1 (1058410), with CAS number 7697-37-2 and empirical formula HNO₃. The diluted acid has a molar mass of 63,01 g/mol, a density of 1,065 g/cm³ and a boiling point above 83 °C. It is supplied in a 100 ml pack for laboratory use as a pharmacopoeia reagent. Identity data from manufacturer Carl ROTH also include EG nr. 231-714-2. The heavy metal-free designation is part of the named Ph. Eur. reagent specification and distinguishes this preparation from general diluted nitric acid. Laboratories following European Pharmacopoeia methods select this reagent when Chapter 4.1.1 calls for nitric acid, diluted, heavy metal-free. The 100 ml unit quantity provides a defined working volume for analytical reagent handling. Density 1,065 g/cm³ assists mass–volume conversion, and the molar mass of 63,01 g/mol supports calculations based on HNO₃. The boiling point above 83 °C is given for the diluted aqueous acid. Review the safety data sheet and apply appropriate laboratory controls when handling nitric acid solutions.
