Nitric acid, diluted R2, Reag. Ph. Eur., 100 ml

Nitric acid, diluted R₂ is a Reag. Ph. Eur. reagent according to Chapter 4.1.1 (1058409), identified by CAS number 7697-37-2 and empirical formula HNO₃. It has a molar mass of 63,01 g/mol, a density of 1,18 g/cm³ and a boiling point above 100 °C. The diluted nitric acid is supplied in a 100 ml plastic pack for laboratory reagent use. Identity and physical data from manufacturer Carl ROTH also include EG nr. 231-714-2. Diluted R₂ nitric acid is the named European Pharmacopoeia reagent of Chapter 4.1.1 and is selected when a monograph or analytical procedure requires this specific preparation rather than an unspecified nitric acid solution. The 100 ml plastic presentation provides a defined working volume for bench-scale dispensing. Density 1,18 g/cm³ supports conversion between mass and volume, while the molar mass of 63,01 g/mol underpins stoichiometric calculations involving HNO₃. The boiling point above 100 °C is given for this aqueous diluted acid. Review the safety data sheet and apply appropriate laboratory controls when handling nitric acid solutions.
