Flame

Title: Flame Test Aim: To determine the cation in each of the unknown substance X, Y and Z by observing the flame colour of different metal compounds. Introduction: A distinctive feature of many s-block metals is their ability to produce flame colours. At temperature of a Bunsen flame, a compound will decompose to give gaseous atoms of its constituent elements. When an electron in the gaseous atom absorbs energy from the flame, it will move from an orbital with lower energy to

1. Yes flame tests are valuable for detecting ions because each metal has a unique line spectrum, which is made up of different wavelength of light that gives off a certain color when heated. 2. The reason to soak the wood splints in distilled water is because if it wasn’t done then it would be harder to receive accurate results. By soaking the wood splints it gave us time to observe the flame color without the wood getting caught on fire. 3. If the unknown mixture were a mixture of two metals then

In the Flame Test Lab we took different ions of salt and put them over a bunsen burner to determine the wavelength of the light. The wavelengths of light visible are in the group visible light: red, orange, yellow, green, blue, indigo, and violet. The colors in which we view an object are reflected off the object, the other colors are absorbed. Each element has a specific color that is given off; it is like a fingerprint. We recorded this data and compared it between the different salt ions, After

The purpose of this experiment is to identify three unknown solutions through the flame test. To attain this purpose, seven known solutions were first tested for their colors as seen in Table 1. To avoid potential contamination, droplets of solution were placed in a watch glass. The nichrome wire was heated with the flame generated by the Bunsen burner. Then, the wire was dipped into solution on the watch glass. Since the watch glass was titled slightly toward the air vent of the Bunsen burner

In Alice Walker's short story, "Everyday Use," Wangero could have thought: "Ashes to Ashes. Dust to Dust." Once the house burned, it, and its history is dead--lost in the flames-- the joy in a new start, a new life, a new name must have made Wangero want to "dance around the ashes (66)" of the house. Dee did in fact change her name to "Wangero Leewanika Kemanjo." When her mother asked her why she didn't use her name anymore Wangero answered: "She's dead, I couldn't bear it any longer being

Flame Lab Part 1. In the first part, a stick with strontium chloride on it was put into flames produced by a bunsen burner. This flame was red from the strontium chloride. The particles moved to an excited state and the color red was the result of the change of state. There was also a high wavelength and a low frequency. Part 2. In part two a stick with copper sulfate was put into the flame. The flame turned green. This is from a decrease in wavelength and an increase in frequency. The particles

burned in a flame test. My study focused on 7 chemicals: Lithium Chloride, Strontium Chloride, Copper 2 Nitrate, Sodium Chloride, Borax, Copper 2 Sulfate, and Potassium Chloride. The hypothesis stated that I believe Sodium Borate, or Borax will burn the hottest. The station was set up for chemical testing, and each chemical was prepped and the nichrome wire was cleansed. I dipped the wire in hydrogen peroxide to clean it, then in water, then in the chemical. While the chemical was in the flame I took

When metals are burned during a flame test their spectrum colors are each unique to their element. To start off, each element during the flame test was burned under a Bunsen burner. Each element showed a special and specific color that was seen through a spectroscope. As shown in the table, lithium was burned and showed a red and orange color. When calcium was burned, it revealed a red, orange, and yellow color. Potassium burned a yellow and orange color, following copper that was burned a solid

Flame Test Lab Questions: 1. What color of light is the lowest in energy? According to our physics class last year, the color with the lowest energy is red because it has the lowest frequency and the longest wavelength out of all colors. We can conclude that calcium chloride has the lowest energy. 2. What color of light is the highest in energy? Violet has the highest energy because it has the shortest wavelength and the highest frequency making it the one color with the highest energy.

Flame Test Practical Explanation The colours displayed in this practical changed depending on the metal chloride solution that was used for example the copper displayed a bright green colour and the lithium displayed a dark crimson red. This is cause by a quantum of heat being transferred into the electrons, exciting them causing them to jump from one ring to another and once the heat has cooled the electrons then return to the lowest possible ring.
