Importance to Humanity
Importance to Humanity
Sodium is essential to all living things, and we can't live without sodium. Our bodies contain about 100 grams of sodium, but it loses in different ways, so we need to ingest sodium like from food.
What's more, it also helps cells to transmit nerve signals, regulate water levels in tissues and blood, and expand the blood volume that accompanies tissue growth.
Where to Find
Where to Find
Sodium is a soft metal that can easily react to the air; therefore, it is never found as the metal in nature. What’s more, it also reacts vigorously with water.
Pure sodium was first isolated by Sir Humphry Davy in 1807 through NaOH. Because sodium can react to the air and water quickly, people usually stored it in a moisture free environment.
