GOST 25794.1
Reagents. Methods of preparation of standard volumetric solutions for acid-base titration
Interstate standard GOST 25794.1 applies to reagents and establishes methods for the preparation of the following titrated solutions for acid-base titration and verification of their molar concentrations:
- sulfuric acid, solutions of molar concentrations:
- c (½ H₂SO₄) = 1 mol / dm³;
- c (½ H₂SO₄) = 0.5 mol / dm³;
- c (½ H₂SO₄) = 0.1 mol / dm³;
- hydrochloric acid, solutions of molar concentrations:
- c (HCl) = 1 mol / dm³;
- c (HCl) = 0.5 mol / dm³;
- c (HCl) = 0.1 mol / dm³;
- sodium hydroxide, solutions of molar concentrations:
- c (NaOH) = 1 mol / dm³;
- c (NaOH) = 0.5 mol / dm³;
- c (NaOH) = 0.1 mol / dm³;
