Understand the roles of the titrant and analyte in a titration: the titrant is the solution of known concentration that is added to react with the analyte, whose concentration is to be determined.
Recall that the titrant is typically placed in a burette because a burette allows precise and controlled delivery of the titrant dropwise into the analyte solution.
Recognize that the analyte (the solution being titrated) is usually placed in an Erlenmeyer flask or a beaker to allow mixing and observation of the reaction.
Note that a graduated cylinder is generally used for measuring volumes roughly but does not provide the fine control needed for titration.
Therefore, at the beginning of the experiment, the titrant should be placed in the burette to allow accurate and controlled addition during the titration process.
