Evaluation of the Uncertainty of Concentration of Sodium Nitrite Standard Volumetric Solution

Shang Jun

Abstract

A method for evaluation of the uncertainty of concentration of sodium nitrite standard volumetric solution was reported in this paper. The calculation formula for the uncertainty was deduced in procedure titration for sodium nitrite standard volumetric solution. The uncertainty for each factor was calculated by analyzing the variable parameters among the procedure. The combined uncertainty was finally obtained by synthesizing the uncertainties for the factors.
