Question

Sodium is a dull-coloured metal. It is very reactive and must be stored in oil for safety.

Chlorine is a pale green, toxic gas. Small amounts are used to disinfect swimming pools.
A reaction between sodium and chlorine produces a white, crystalline solid, which is commonly known as table salt.

Q: Explain why it is difficult to get chlorine out of sodium chloride.

Answer 1

Hi there!

It is difficult to remove chlorine out of sodium chloride because in order to separate them you must put that energy into the salt.

Chlorine gas is toxic, and extremely irritating to the eyes and mucous membranes.
