Summary

This video demonstrates the process of using an ion exchanger in a laboratory setting. The equipment setup includes tanks, pumps, and columns to house cation and anion resins. The procedure begins with preparation, followed by checking safety equipment, electrical connections, and the pump. The ion exchange process is conducted by running a calcium chloride solution through the system. Samples are taken, tested for turbidity, and compared before and after ion exchange. The video highlights the importance of proper setup, monitoring, and recording results during the experiment.

Takeaways

• 😀 Safety preparation is key; wear gloves and a lab coat before starting the experiment.
• 😀 Ensure that all equipment is functioning properly before proceeding with the experiment.
• 😀 Check electrical connections by turning on the pump and verifying the fluid flow.
• 😀 The ion exchange process involves using resin columns to exchange cation and anion particles.
• 😀 After starting the pump, allow the solution to flow for about 1 minute to collect samples.
• 😀 Inspect pipes during the process to ensure there are no leaks.
• 😀 Chemical tests include mixing distilled water with NHCO3 and checking for turbidity.
• 😀 The CaCl2 solution shows turbidity when mixed with NHCO3, indicating the presence of ions.
• 😀 After ion exchange, the solution should remain clear, showing successful ion removal.
• 😀 Record the results of each test, including volume used and any observations, in the jobset.
• 😀 Follow the chemical reactions based on literature references to verify the outcomes of the ion exchange.

Q & A

What is the primary objective of this experiment?

The primary objective of this experiment is to demonstrate the process of ion exchange using different resins for cations and anions, and to test the effectiveness of ion exchange by observing the changes in the solution after treatment.

What safety equipment is used during the experiment?

The safety equipment used includes gloves and a lab coat (jobset) to ensure protection during the experiment.

What is the role of the CACL 21% solution in this experiment?

The CACL 21% solution is used as the starting material in the ion exchange process, where it interacts with the resins in the ion exchange columns.

What does the initial check of the equipment include?

The initial check involves verifying the functioning of the pump, ensuring that the pump and the tank are operating properly. If everything works fine, a checkmark or strip is noted.

How long is the solution run through the system in the experiment?

The solution is run through the system for about 1 minute, as only a small sample (10 mL) is required for testing.

What happens if there is a leak in the pipes or connections?

If a leak is detected in the pipes, it is noted in the jobset as part of the troubleshooting process. However, no leaks were reported in this particular experiment.

What reagent is added to the sample to test for ion exchange results?

To test the ion exchange results, sodium carbonate (NaCO3) solution is added to the samples in the reaction tubes.

What is observed when the CACL solution is mixed with sodium carbonate?

When the CACL solution is mixed with sodium carbonate, a slight cloudiness or turbidity is observed, indicating the presence of calcium ions in the solution before ion exchange.

How is the sample after ion exchange different from the original sample?

After ion exchange, the sample shows no turbidity, indicating that the ions responsible for the cloudiness (like calcium) have been removed, and the solution is clearer compared to the pre-ion exchange sample.

What steps are involved in checking the results after ion exchange?

To check the results after ion exchange, a sample from the ion-exchange tank is taken and treated with sodium carbonate, then observed for clarity. The comparison between the pre- and post-ion exchange samples helps in determining the effectiveness of the process.
