| Abstract: |
| The impact factors in the uncertainty of measurement of volumetric solution concentration were analysed using the theory of assessment and expression of uncertainty monitoring with the example of the determination of the concentration of sodium nitrite volumetric solution. The factors effecting on the uncertainty of measurement in the determination of the concentration were evaluated, including repeatability of measurement results, balance, burette, the purity of standard reagent, etc. The expanded uncertainty was 0.0001 mol/L. |
| Key words: sodium nitrite volumetric solution, concentration, uncertainty of measurement |
