摘要
Abstract
As the basis of inorganic chemical analysis and testing,the accuracy of standard solutions directly affects the test results and should be highly valued by laboratories.A standard titration solution is a solution with a known accurate concentration and is usually used for titration analysis to determine the content of the substance to be tested.Its configuration process needs to follow high-precision specifications to ensure the accuracy of the concentration.In chemical analysis experiments for quality testing,testing personnel not only need to have professional chemical analysis operation capabilities,but also need to master corresponding computing capabilities.This paper aims to systematically summarize the calculation methods of uncertainty of general standard solutions and deeply analyze the sources of errors in titration analysis.Clarifying the calculation method and error sources can provide a theoretical basis for the laboratory to optimize the management of standard solutions and improve the reliability of analysis results,and has practical guiding value for ensuring the accuracy and standardization of chemical analysis.关键词
