Why is sodium not used to make cutlery?
Here are a few good reasons:First, sodium is highly reactive with water and dissolves in an exothermic reaction so that the hydrogen released will ignite. So cutlery made from sodium would be a one shot affair and would likely result in your meal exploding.Secondly, as a metal sodium is very malleable and would only be good for soft food.A high sodium diet is simply not healthy.Elemental Sodium Metal is extremely reactive with water, and will even react with the moisture in air. It would be dangerous to use it to cut anything that would contain the slightest bit of moisture... and would even be dangerous to handle with one's own hands.... especially sweaty hands. It could explode into flames if ever washed in water.Sodium Chloride actually is a wonderful substance. It is extremely hard, but also brittle. But, unfortunately it will dissolve readily in water. So, it would either break on usage, or would dissolve in contact with food containing significant amounts of water, or if someone ever washed it in water.It is noted that Sodium Chloride disks are often used for IR Spectroscopy, and they can last a very long time if well cared for and never allowed to touch water.
