Study Notes
Titration
- Titration is a chemical technique that involves slowly adding a solution of known concentration (titrant) to another solution of unknown concentration (analyte) until the reaction is complete.
- This helps determine the exact amount of the unknown substance in the solution.
Titration Apparatus
- Burette is the main laboratory apparatus used during titration.
- Stopcock (on burette): Controls the flow of liquid.
- Conical flask: Used to hold the analyte solution.
- White tile: Used as a background to observe color changes during titration.
- Buret clamp: Holds the burette in place.
Titration Components
- Analyte: The substance of unknown concentration being measured in the titration.
- Titrant: The solution with a known concentration, carefully added to the analyte during the titration.
- Indicator: A substance that changes color at the endpoint of titration, helping visually identify when the reaction in titration is complete. Examples include phenolphthalein, bromothymol blue, and methyl orange.
- Endpoint: The point in a titration where the indicator changes color, signaling the reaction between the titrant and analyte is complete.
Learning Competencies
- Define titration and its components.
- Identify laboratory apparatuses used during titration.
- Perform a simple acid-base mini-titration.
- Cultivate a sense of curiosity and inquiry about chemical reactions.
Pre-Assessment/Test Questions
- Common indicator for titration (e.g., phenolphthalein).
- Color change indicating reaction completion (visual indication with an indicator).
- Main laboratory apparatus used for titration (burette).
- Substance in titration whose concentration is unknown (analyte).
