What is happening in flame test lab?
In a flame test lab, various metal ions are tested by placing a small sample of the compound in a flame, which produces a characteristic color. This color is due to the electrons in the metal ion moving to higher energy levels and then back down to their ground state, emitting light of a specific wavelength. By observing the color produced, one can identify the metal ion present in the compound.
How are electron excited in a flame test anylses?
In The name of God Introduction: Flame test is method to identify the element (metal ions) based on Emission spectrum. The test involve putting sample of Unknown element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which make the color back to normal. Then compare it to flame test result of former lab but after testing it with cobalt blue glass. Material: 1- Safety Goggles 2- 250 mL beaker 3- 500 mL beaker 4- Bunsen burner 5- Cobalt blue glass 6- Distilled water 7- Flame test wire 8- Dropper 9- Test plate with walls 10- Spectroscope 11- HCl solution 12- Unknown Solution Number 6 Procedure: 1- Small amount of HCl was added to small 250 mL beaker. 2- The Bunsen burner was lighted. 3- The flame test wire was dipped into the HCl for minute then heated by holding it in the Bunsen burner for another minute or until all the red color is gone. 4- The flame test wire was cooled and then rinsed with distilled water into 500 mL beaker. 5- Full drop of unknown solution # 6 was added to test plate. 6- The flame test wire was dipped into unknown # 6 Solutions. 7- Then the flame test wire was put to fire. 8- The procedure No. 3&4 were repeated to clean the flame test wire. 9- The flame test was dipped again in the Unknown solution # 6. 10- Blue Cobalt glass was used to test the color. 11- The flame test wire was put to fire while holding the blue cobalt glass.

Do you have to be NPO for a PT lab test?
It depends on the specific lab test being conducted. Some lab tests require fasting (NPO) to obtain accurate results, while others do not. It is best to follow your healthcare provider's instructions regarding fasting before a lab test to ensure accurate results.
Why does a flame not get extinguished when a wire gauze was placed on top of it in a candle observation chemistry lab?
A flame is not extinguished when a wire gauze is placed on top of it because the flame is still exposed to oxygen. The gauze has holes, through which oxygen can flow. Additionally, oxygen can reach the flame from under the gauze. Consequently, the flame is not extinguished.

Why are the metals in a flame lab test used in a chloride compound instead of just by themselves?
Metals are used in a chloride compound in a flame test because the chloride compound helps to enhance the visibility of the colored flame. When the compound is heated in a flame, the metal ions in the compound absorb energy from the heat and emit light in specific colors, making it easier to identify the metal present.
How do you heat a test tube?
You boil some water and put the test tube in and its heated up but you don't have to worry about a flame. You boil some water and put the test tube in and its heated up but you don't have to worry about a flame. To heat a test tube you simply use a Bunsen burner. Make sure you use pliers to hold it with though because it will get very hot. Also you can change the heat of the Bunsen burner by switching it to the blue flame. you always hold it away from you and your lab partner. heat it sideways and slowly run it through the flame to distribute the heat evenly.
What type of drug test detect k2?

In a flame test what color flame will barium chloride have?
Barium chloride, or any other barium salt, should burn with a green flame. When a barium salt is burned, the thermal energy is transferred to the outer electrons of the barium ions. They gain enough energy to excite them to a higher energy level. They then drop back to their ground state, releasing energy. This energy corresponds to a wavelength of light, which is emitted from the ion. This wavelength corresponds to green light, hence the green flame observed.
