Flame Color. Next, flame tests were conducted with a solution of 0.1 g 643p in l mL distilled H2O and samples of the remaining possible compounds with the same concentration. A wire loop was cleaned and dipped into the solution and held over the hottest part of the flame of a Bunsen burner. This procedure was completed for the each solution, cleaning the wire loop between each test to avoid contamination and recording and photographing each flame color and…
2. Heat each test tube gently over a Bunsen burner flame and record your observations in your notebook.…
* Safety, no exposed skin, always wear gloves, Wear long sleeves, long pants, closed shoes, and goggles, always work 6 inches inside the hood, cover chemicals when transporting between hoods, report any accidents immediately, use Aspirator when solvent is Organic, Use Vacuum when solvent is Aqueous, neutralize all acids and bases for cleanup and disposal…
The purpose of the Types of Chemical Reactions lab is to become familiar with the different types of chemical equations. Also the experiment allows one to apply their equation skills to explain reactions. This is done by heating compounds with the Bunsen burner and also by mixing compounds in the twenty four well plate. The experiment found that the liquid compounds reacted to form milky liquids. Also that the heated solids caused condensation that put the fire on the splints out. The experiment could have been flawed due to measurements.…
I placed about 0.5 mL of 8 different chemicals into 8 different places in the 24-well plate. I then lit the handy wick to keep a flame burning. I soaked a cotton swab in the first chemical and moved the cotton swab in and out of the flame rapidly to see the flame color change. I then repeated this process for the rest of the chemicals.…
Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame…
Specifically explain how the colors in the flame tests are produced. You must include the following terms in your answer: energy, energy levels, electrons.…
1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame…
4. Obtain an unknown from your teacher, record the letter of the unknown, and do a flame test on the unknown. It will be one of the chemicals you have already tested.…
Imagine you are a tour guide for a major chemical laboratory. Write a short script for the tour that summarizes what the scientists should (or shouldn’t) wear in the lab, what safety precautions they take, their rules for cleanliness, and what they do in case of an accident. Your script should contain at least ten of the rules/information from the lesson. (30 points)…
The purpose of this lab was to find out the properties and characteristics of a candle. Also the purpose was to find the remnants that the combustion of a candle leaves behind as gas. I learned that the candle that is burning releases a certain gas into the air. I also learned that limewater has a chemical reaction when exposed to that gas and turns red.…
In this experiment, you will perform the flame tests used to identify ... In this lab, the solutions you will be using contain harmful materials. Avoid skin contact with ...…

In a lab, you must always make safety a priority in case of an emergency. In our lab, we made sure to wear closed-toed shoes as well as goggles at all times. We also performed part of our experiment in a fume hood in order to protect ourselves from any potentially dangerous fumes. We made sure not to touch the hotplate, and also to use tongs when picking up a hot beaker.…
Other safety concerns associated with this exercise are basic lab precautions, including keeping a clean workspace, washing your hand after dealing with chemicals and blood, and using precaution when obtaining blood samples. In order to ensure that this occurs, layout the equipment beforehand in a clean sterile environment and clean the work space after experiment. By doing so, this reduces the risk of contamination or cutting yourself when using the tools. Use gloves, masks, and goggles at all times.…
