Standardization and Quality Control in Chemical Industry Experiment
Experiment Overview
This experiment aims to demonstrate the significance of standardization and quality control in the chemical industries. It involve the standardization of a NaOH solution using a standard solution of HCl and subsequent use f standardized solution in an acid-base titrations.Materials and Equipment
- Potassium Hydrogen Phthalate (KHP)- Sodium Hydroxide (NaOH)
- Hydrochloric Acid (HCl)
- Standardized Solution of HCl
- Volumetric Flasks (50mL, 100mL)
- Burette (50mL)
- Pipette (10mL)
- Analytical Balance
- pH meter
- Magnetic Stirrer
- Beaker (250mL)
Experimental Procedure:
Step 1: Preparation of KHP Solution- Weigh accurately about 0.2g of KHP and transfer it into a 100mL volumetric Flask.
- Dissolve KHP in deionized water and mix thoroughly.
- Fill the volumetric Flask to the 100mL mark with deionized water and shake well.
Step 2: Standardization of NaOH Solution
- Using a burette, transfer 20.00mL of the standardized HCl solution into a 250mL conical Flask.
- Add 2-3 drops of phenophthaline solution as an indicator.
- Slowly titrate the standardized HCl solution with the NaOH solution from the burette under constant stirrig.
- Record the volume of NaOH solution required to reach the phenophthaline end point (color change from pink to clear).
- Calculate the concentration (in Molarity) of NaOH solution using the following equation: Concentration of NaOH (M) = (Standardized HCl Molarity x Volume of HCl) / Volume of NaOH
Step 3: Acid-Base Titration
- Take a 10.00mL aliquot of the KHP solution into the 250mL conical Flask.
- Add 2-3 drops of phenophthaline solution as an indicator.
- Titrate this solution with the standardized NaOH solution from the burette under constant stirring.
- Record the volume of NaOH solution required to reach the phenophthaline end point.
- Calculate the concentration of KHP solution (in Molarity) using similar equation as above.
Step 4: Quality Control Evaluation
- Calculate the percentage error in the determination of KHP concentration by comparing it with the theoretical concentration.
- Discuss the importance of standardization and quality control in the chemical industry.
Key Procedure:
- Standardization of NaOH Solution: This process involves the use of a standard solution of HCl to determine the exact concentration of the NaOH solution. The accurate result is critical for precise acid-base titrations.- Acid-Base Titration: This is a technique use to determine the concentration of an unknown acid or base by reacting it with a known concentration of a base or acid, respectively. The experiment demonstrated the use of standardized NaOH solution to determine the concentration of KHP solution.
- Quality Control Evaluation: The percentage error in determining the concentration of KHP is used as a metric to evaluate the accuracy and precision of the experiment.
Significance:
- This experiment highlight the importance of standardization in chemical industry. Standardized solutions are essential for various analysis, ensuring accurate and reliable results.- It showcases the application of standardized solution in acid- base titrations, which is widely used in chemical analysis and quality control.
- The experiment demonstrate the need for quality control in the chemical industry to ensure product quality and compliance with specifications.
