Potassium Firework Facts

Symbol: K

Name: Potassium

Use: Potassium helps to oxidize firework mixtures. Potassium nitrate, potassium chlorate, and potassium perchlorate are all important oxidizers. Potassium produces a purple color, but it is easily overpowered by sodium (yellow), since the human eye is not very sensitive to the violet end of the visible spectrum.
