Titration experiment of magneticstirrer and its precautions

After the magnetic stirrer is introduced into the titration operation process, the working pressure of the operator is greatly reduced. In the past, in the titration operation of volumetric analysis, the operator used the manual stirring method to carry out the titration and stirring, which not only made the titration operation cumbersome and labor-intensive for the analyst, but also often caused insufficient stirring, especially near the end point. It is difficult to master the coordination of stirring speed and titration speed, which will bring certain operational errors to the analysis results. The introduction of the magnetic stirrer solves various adverse effects caused by manual stirring, and makes the titration operation more standardized and programmed.
