Experiment: Titration of an Acid Solution

Objective:

To determine the concentration of an unknown acid solution through titration with a standardized base solution.

Materials:

Unknown acid solution
Standardized base solution (e.g., sodium hydroxide, NaOH)
Burette
Pipette
Erlenmeyer flask
pH meter
Phenolphthalein indicator

Procedure:

Pipette a known volume (e.g., 25 mL) of the unknown acid solution into an Erlenmeyer flask.
Add a few drops of phenolphthalein indicator to the flask.
Fill a burette with the standardized base solution.
Slowly add the base solution to the acid solution while swirling the flask constantly.
Monitor the pH of the solution using the pH meter.
Record the volume of base solution added when the endpoint is reached (color change from colorless to pink).

Key Procedures:

Accurate measurement of volumes using pipettes and burettes.
Careful monitoring of the pH to determine the endpoint.

Significance:

Standardization of industrial chemical processes involves ensuring that processes are consistent and produce products of specified quality. Titration is a fundamental technique used in industrial settings to control the concentration of chemicals in various processes.

By determining the concentration of the unknown acid solution, this experiment demonstrates the importance of accurate measurements and standardized procedures in ensuring the quality of products and maintaining optimal process conditions.
