Have you used the right Titrator?
Titration is a quantitative method for determining the concentration of a compound (acid-base, Chloride ions / metal compounds) by reacting with titrants with known concentrations.
In the learning lab (school / campus) titrations are often forgotten with titrants in the burette related to the stative, while for routine work in the research and industrial labs often auto titrators are found as an alternative to more effective and efficient titrations. Which is the best for you?
In manual titration, the titran discharge from the burette is controlled by the user’s hand, while in the auto titrator the titrant discharge can be precisely controlled by volume and speed. Detection of end points on a manual titration is based on changes in the color of the analyte, whereas on the auto endpoint the titrator is detected automatically by the electrode.
So, have you used the right titrator?
