Its electrons are excited to a higher energy state in the flame, and then they immediately release that energy, which is visible as yellow light.
Flame tests are often used to identify metals and other substances, such as sodium. If you expose the element sodium to flame, it will give off a bright, vibrant yellow color.
well , the colour of potassium chloride is a lilac colour :) hope this helps
You can do a flame test. Sodium will make the flame turn an intense yellow. See: http://en.wikipedia.org/wiki/Flame_test
- use a flame test to distinguish between sodium and potassium - use flame photometry to determine sodium and potassium - heat sodium carbonate and collect the gas in a beaker with water: the gas released is carbon dioxide; see the bubbles. Measure the pH; it will be more than 7.
All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
Sodium chloride (salt) gives a yellow-orange flame result.
No, sodium chloride is a very stable compound
It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.
Get a wire. Bend it into a ring and put a few crystals of your solid on it. Do a flame test using a Bunsen burner. Potassium will give a violet flame and Sodium ions will give a Yellow flame.
There would be electron transitions in sodium atoms while the flame test. The majority of them would emit photons which would have same energy and frequency corresponding to yellow color.
It is recommended to use the sodium chloride solution; the color in the flame test is yellow.
When sodium is subjected to a flame test, it burns a bright yellow. This yellow flame can be brighter than the lilac flame color of the potassium, which makes it more difficult to distinguish between the sodium and potassium.
