Flame test

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

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. Errors - Contamination - Flame Heat - The ring

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

Experiments were conducted to test the heat along with different variables of certain chemicals when 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

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 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

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.

The flame test lab was to test what kind of element the substance was if it was an unknown element, or if the element was known then it would be to see the reaction that the element would have with the open flame based on its energy level. The flame test works by placing a q-tip into the water so the substance easily sticks to it and won’t come off. Then the substance is introduced to the flame by putting the q-tip over the flame and based on the colors it can be determined what kind of element it

Flame Test Purpose: The premise of the lab experiment was to observe the color of visible light emitted from several compounds and find what the unknown substance is by comparing its reaction to others. The emission of light, more so, occurs when an electron releases absorbed energy from its excited state and reverts back to a position of lower energy, a ground state. Procedure: In order to achieve the results for the experiment, a Q-tip was used to place near the Bunsen burner. The Q-tip, lightly
