Jordyn: Welcome to WTMI Productions Philip: We are about to embark upon a journey
of scientific discovery. And what you are about to experience just might change how
you see the world around you. [Fancy Music/Montage]
Alyssa: Salt Philip: Salt
Jordyn: Since the beginning of humanity itself, sodium has played a key role.
Alyssa: Perhaps its first chemical use was in the formation of glass.
Philip: The egyptians called sodium carbonate, or soda, natron.
Jordyn: The Romans used the term natrium, hence the symbol Na.
Alyssa: But sodium carbonate is not the only place sodium is found.
Philip: In fact you might say sodium is a part of every one of us - literally.
Jordyn: Sodium plays key roles in cell processes. Alyssa: In its ionic form, sodium maintains
electrical gradients. Philip: Ironic? No, ionic.
Jordyn: Sodium in its pure form was discovered by Sir Humphrey Davy in 1807.
Alyssa: Davy ran a current through sodium hydroxide to separate out the pure sodium.
Philip: Pretty sweet, huh? Or should I say salty...
Jordyn: Sodium, in its pure form, is highly reactive.
Alyssa: Like all alkali metals, sodium easily gives up an electron to react with other elements.
Philip: So combining things like water and sodium...

Jordyn:Sodium in its many compounds does all kinds of stuff
Alyssa: Table salt Philip: Baking soda
Jordyn: Sodium alginate, a thickening agent Alyssa: Sodium biflouride, a preservative.
Philip: Sodium fluorosilicate, used to make flouride in toothpaste
Jordyn: And sodium metaborate, a herbicide, among others.
Alyssa: In short, sodium is a crucial of the world around us.
Philip: From heights of mount kilamanjro to the methane vents deep beneathh the atlantic
ocean. Jordyn: Thank you for watching
