Sodium Reacts with Liquid Water

http://www.FreeScienceLectures.com Sodium is a chemical element which has the symbol Na (Latin: natrium), atomic number 11, atomic mass 22.9898 g/mol, oxidation number +1. Sodium is a soft, silvery white, highly reactive element and is a member of the alkali metals within "group 1" (formerly known as 'group IA'). It is classified as an "inorganic macro-mineral". t has only one stable isotope, 23Na. Sodium was first isolated by Sir Humphry Davy in 1807 by passing an electric current through molten sodium hydroxide. Sodium quickly oxidizes in air so it must be stored in an inert environment such as kerosene. Sodium is present in great quantities in the Earth's oceans as sodium chloride. It is also a component of many minerals, and it is an essential element for animal life. This video shows what happens if you place a piece of sodium in water. It does not react as quickly as potassium or lithium. The reaction is slower, initially causing it to burn and as the temperature rises, it is probably broken into more pieces, exposing more surface area to water, the reactions speed up and the piece explodes. --- It's Never too Late to Study: http://www.FreeScienceLectures.com --- Notice: This video is copyright by its respectful owners.
