<reasoning>

Identify titration components

In a standard laboratory titration setup, a solution of known concentration is added to a solution of unknown concentration to determine its concentration.

Define the titrant

The solution of known concentration that is added from the burette is called the titrant. In the diagram, the burette is the vertical graduated tube held by the clamp. Therefore, the liquid inside the burette is the titrant.

Define the analyte

The solution of unknown concentration being analyzed is called the analyte (or titrand). This solution is placed in the Erlenmeyer flask beneath the burette. Therefore, the liquid inside the flask is the analyte.
</reasoning>

<answer>

• Titrant: The solution inside the burette (the vertical tube).
• Analyte: The solution inside the Erlenmeyer flask (at the bottom).

</answer>
