Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Potassium are as follows: - Color : Silver-white
- Phase : Solid
- Melting point : Melting point of 63°C (145°F) - very low for a metal
- Color : Silvery-white metal
- Density : Less than water
Potassium Properties - What are the Chemical Properties of Potassium?
What are the Chemical Properties of Potassium? They are the characteristics that determine how it will react with other substances or change from one substance to another. The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Potassium are as follows: - Chemical Formula : K
- Reactivity with water : It reacts with water violently and gives off hydrogen gas
- Reactivity : It reacts readily with all acids and with all non-metals, such as sulfur, chlorine, fluorine, phosphorus, and nitrogen
Highly or explosively reactive - Compounds : Useful compounds include the bromide, KBr, the cyanide, KCN, Potassium carbonate K2CO3. Substances containing potassium impart a purple color to a flame
- Oxidation : Rapidly oxidizes in air
- Alloys : Alloyed with sodium as a cooling medium in nuclear reactors
