Question

What are two uses of sodium chloride?

Answer 1

Sodium chloride (NaCl), commonly known as salt, is one of the most abundant minerals on Earth and an essential nutrient for many animals and plants. It is naturally found in seawater and in underground rock formations

Many people use it as...

food seasoning

clearing up icy roads (i.e. freezing point depression)

Some potentially weird or inventive people use it for:

sponge restoration (soak it in a quarter cup of salt per liter of water or so)

keeping your windows not frosty (make a salt water solution and rub your windows with a rag).

Put out small fires (salt has a high melting point, and can smother it).

Remove baked-on food from pan (soak in salt water, then rub it off)
