Titration:
Titration is a widely used method to determine the concentration of sodium chloride in a solution. In this method, a solution of known concentration (titrant) is slowly added to the solution containing sodium chloride until the reaction between the two is complete. The endpoint of the reaction is usually indicated by a color change or a sharp change in pH.
Process:
1. Prepare a solution of sodium chloride whose concentration needs to be determined.
2. Add a few drops of an indicator that changes color when the reaction is complete.
3. Slowly add a titrant solution of known concentration to the sodium chloride solution while stirring.
4. Continue adding the titrant until the indicator changes color permanently.
5. Note the volume of titrant used to reach the endpoint.
6. Use the volume and concentration of the titrant to calculate the concentration of sodium chloride in the solution.
Advantages of Titration:
- It is a simple and accurate method for determining the concentration of sodium chloride.
- It does not require expensive equipment and can be performed in a laboratory setting.
Limitations:
- The accuracy of the method depends on the skill of the person performing the titration.
- The presence of other ions in the solution may interfere with the reaction, leading to inaccurate results.
In conclusion, titration is a reliable method for determining the concentration of sodium chloride in a solution and is commonly used in analytical chemistry laboratories.
