What Colour flame does potassium burn in air?
lilac flame
Small pieces of potassium heated in air tend to just melt and turn instantly into a mixture of potassium peroxide and potassium superoxide without any flame being seen. Larger pieces of potassium burn with a lilac flame.

What color does the flame turn when potassium chloride is inserted?
light lilac
Potassium Chloride: light lilac. Sodium Chloride: yellow flame. Strontium Chloride: red or crimson flame.
Will potassium nitrate explode?
POTASSIUM NITRATE mixed with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979.
What Colour flame is seen when potassium reacts with water?
When potassium is added to water, the metal melts and floats. It moves around very quickly on the surface of the water. The metal self-ignites, which also ignites the hydrogen gas. This results in sparks and a lilac flame.
What color flame is magnesium?
Normally one demonstrates magnesium burning by getting it started in the Bunsen flame, and then removing it so that it burns in air with a blinding white light. The product is a white smoke. This product can be collected by burning the magnesium under an inverted beaker, showing it is a solid, a white ash — MgO.
What color is rubidium flame?

What does blue flame indicate?
A natural gas blue flame indicates that the burner is providing the correct air-fuel mixture, with sufficient oxygen for complete combustion at the burner. A blue flame burns the fuel completely producing carbon dioxide, water and heat.
What causes a flame to be blue?
The bright orange of most wood flames is due to the presence of sodium, which, when heated, emits light strongly in the orange. The blue in wood flames comes from carbon and hydrogen, which emit in the blue and violet. Copper compounds make green or blue, lithium makes red.

Can a silver wire be saturated with potassium chloride?
As noted above, changing the electrolyte concentration changes the electrode potential. Silver chloride is slightly soluble in strong potassium chloride solutions, so it is sometimes recommended the potassium chloride be saturated with silver chloride to avoid stripping the silver chloride off the silver wire.
Can you use potassium chloride with silver chloride?
Silver chloride is slightly soluble in strong potassium chloride solutions, so it is sometimes recommended the potassium chloride be saturated with silver chloride to avoid stripping the silver chloride off the silver wire.
