Bunsen burner

Potassium Bromide were first tested by putting a candle underneath a sample of the compounds. The compounds did not melt which told us that they did not have a low melting point. Sodium Chloride and Potassium Bromide were then tested by putting a Bunsen Burner…

Francisella tularensis is a bacterium that has been recognized to be an agent responsible for the disease known as tularemia. This disease, in essence, sends the immune system of the organism into a hyperactive state, sometimes referred to as hypercytokinemia due to the elevated levels of various cytokines, which if not treated properly could lead to extremely high fevers, inflammation of various tissues, and (if contracted through aerosol form) the death of the infected organism. Specifically,…

A Bunsen burner was used to heat the beaker and we were able to measure it by using a thermometer. We also used ice to lower the temperature of the water. In some cases, we needed to measure the pH by using the strip and analyzing by comparing it to the…

needed to completely dissolve the salt. The cation test told whether the unknown contained barium, calcium, potassium, sodium, strontium, lithium, copper, or magnesium. Given a chart of the colors that each burn, lit the unknown on fire with a bunsen burner and compared the flame color with the colors in the chart. In order to identify the anion, we needed to perform four anion reactions: chloride, sulfate, nitrate, and carbonate. To identify a chloride, equal amounts of the unknown…

prevented. PROCEDURE: Smear of organisms to be stained were prepared. & the smears were heat fixes. The slide was Place on wire gauze on a ring stand. The slide was Saturate with carbolfuschin. The slides were heated with a hand –held Bunsen burner until steam can be seen rising from the surface. The slide was heated to maintain steaming for 3-5 min. As the slide begins to dry during the staining process add a drop or two of carbolfuschin was added to keep the slide moist. At the end…

For this experiment, a group was employed by the Environmental Protection Agency as analytical chemists. Their goal was to identify an unknown compound that has been discovered in a landfill in their hometown. Once they identified the compound, they would then have to determine both the chemical and physical properties of the compound in order to inform the townspeople of any potential dangers. During the first week of lab, the group was given a small bottle containing an unknown white…

measurements and procedures were used when solutions of calcium chloride and nitric acid were created using separate beakers. Portions of each solution were then poured into test tubes (exact measurements were not necessary for this step). After the bunsen burner was turned on, and the flame was gauged to be of adequate length (must be able to see changes in color), a nichrome wire was dipped into the test tube of the unknown, and then the solution-covered segment of the wire was placed into the…

“The most tangible of all visible mysteries-Fire,” said by Leigh Hunt brings us to think how amazing and destructive something so beautiful can be. Fire is considered one of the four basic elements and the fact is that nothing is basic about fires. The chemical process that occurs is what we see when the fire dances in front of our eyes. In the safety field there is an increased need for fire knowledge so that we can prevention and train employees on them. There are many components to consider…

the compounds into the capillary tubes. The procedure was a very good method for finding the purity and melting points of compounds due to the easy at which the melting is noticed as well as being able to control the temperature unlike using a Bunsen burner or a hot…

“She’s such a nice person.” “She’s the nicest person in the group.” Nice. The one word that I constantly hear when someone is asked to describe me or the word just pops up into the conversation. I take it as a compliment, because it still is, but that word isn’t my only defining characteristic. I am passionate, attentive, and adaptive in any task that I have accomplished in my life so far. Not many people can say that they are passionate, even fewer can say that they know what they are…
