Standard titres sodium tetraboric acid / sodium tetraborate fixanals

Standard titres sodium tetraboric acid application

The solution prepared from standard titres is used in chemical analysis for standardisation of HCl, H2SO4 and HNO3 acid solutions and determination of their concentration.
Under the conditions of storage at a temperature not exceeding 25°C without access to carbon dioxide, the solutions can be used repeatedly, until turbidity, for several weeks.
Sodium tetraborate solution obtained from fixanal Sodium tetraborate acid solution has a precisely defined volume and molar concentration of equivalent 0.100+0.001 mol/dm3

To obtain a solution of borax fixanal, the preparation is poured into a laboratory flask, distilled water at 20°C is added and thoroughly mixed. Then the obtained solution is brought with distilled water to a volume of 1000 cm3 and mixed again.
