Chromotography Lab Essay Example

to take both this book as well as the bottle containing chemicals along with you wherever you goTo safely identify chemicals, hold them six inches away from your nose and wave your hands over the container's opening towards your nose. Gently waft some fumes towards your nose without exposing yourself to a large dose of anything unpleasant or dangerous. It is crucial not to taste any of the chemicals used in these experiments.

In order to minimize the risk of ingesting unfamiliar chemicals, refrain from eating or drinking in the laboratory. After conducting experiments, always remember to clean your hands and lab area. Promptly clean up any messes to maintain a tidy lab space.

If poisons are used or produced during this experiment, follow the directions provided in the lab manual for proper disposal. Engaging in horseplay can lead to chemical spills, accidental fires, broken containers, damaged equipment, and injuries. Be cautious with objects and avoid wrestling, punching, or shoving while in the lab.

Ensure you have a first aid kit containing gauze, band-aids, baking soda ointments forceps scissors hydrogen peroxide ,and a chemical cold pack prepared if one is not already available. Report all accidents to your instructor and seek assistance for any unrelated fire incidents that may occur during lab activities.Please familiarize yourself with the location and usage of a fire extinguisher. It is important to know where to find it and how to use it. In the event that your clothes catch fire, remember to stop, drop, and roll.

While working in the laboratory, it is essential to wear safety glasses. The objective of this lab is to identify certain physical properties of matter by conducting simple tests on substances found on the moon.

In the discussion section, we will explore how properties like color, shape, density,and viscosity classify different types of matter and determine their practical uses. However, it should be noted that these common properties have limitations.

For instance if we describe a fruit as a solid object with an elliptical shapeand smooth outer covering containing a crispy inner part with tiny seeds,it most likely refers to an apple.
The exact type of apple, whether it be a Macintosh, Red Delicious, or Granny Smith variety, is impossible for us to determine. To provide a more detailed description of an apple, we can mention that Area Delouses are suitable for eating raw while Moonstones are best for making applesauce. By emphasizing the culinary characteristics of apples, we highlight their distinct qualities that differentiate them from each other. This activity involves categorizing matter by examining the physical properties of different substances. The materials needed include paper towel, cloth towel, plastic wrap (such as Saran wrap),

sponge, colored liquid (like juice), steel (such as a nail or hammer head), copper (like wire or penny), aluminum (like a nail, pan or soda can), glass bottle , chalk piece, wood (like a popsicle stick), hammer, pencil lead string and toothpick rubber band. To conduct the experiment and make observations: 1. Absorbency: Dip a piece of paper towel in the colored liquid and observe its reaction. Repeat this process using a scrap of cloth towel, plastic wrap and a sponge. Take note of any differences noticed. 2.Hardness: Use steel to attempt scratching copper, aluminum, glass wood,and chalk.Record whether the nail was able to scratch each substance in the provided chart.
