a neat spectrum of liquid with a boiling point of 150 degrees celcius determined using salt plates
I see no question.
Provide a alternative method for a neat spectrum of a liquid with a bioling point of 35 degress celcius using salt plates. how does the solubility of running the infrared spectrum under this?
To create a neat spectrum of liquid using salt plates to determine the boiling point of a substance, you can follow these steps:
1. Start by placing a small amount of the liquid sample in a clean and dry watch glass or small container.
2. Obtain a pair of salt plates, which are usually made of sodium chloride (table salt) and have a high melting point.
3. Carefully heat the salt plates in an oven or on a hot plate until they are evenly heated. It's important to use salt plates because they have a high thermal stability and can withstand high temperatures.
4. Once the salt plates are heated, remove them from the heat source and place them on a heat-resistant surface.
5. Using a spatula or a glass rod, transfer a small drop of the liquid onto one of the salt plates. Be cautious not to touch the salt plate too much to avoid contamination.
6. Immediately place the second salt plate on top of the liquid drop, sandwiching it between the two plates.
7. Press the salt plates gently together to spread the liquid in a thin film between them. Make sure the liquid is evenly distributed across the surface.
8. With the liquid trapped between the salt plates, carefully observe it under a bright light source. You can use a flashlight or a lab light source to illuminate the spectrum for better visibility.
9. As the temperature of the salt plates increases, the liquid will begin to vaporize, resulting in different colors or patterns. These colors or patterns can indicate the boiling point of the liquid.
10. Monitor the changes in color or patterns closely as the temperature rises. The boiling point of the liquid is typically the temperature at which you observe a rapid and distinct change in the spectrum, such as the disappearance of certain colors or the formation of new patterns.
Remember to perform this experiment in a well-ventilated area and follow all necessary safety precautions, including wearing appropriate protective equipment such as goggles and gloves.
