Hi eggse, I think you are asking about the salt in Chemistry?
On the basis of chemical reaction, different types of salts are formed. Most common is the “table salt” which is made up of Sodium and Chloride (NaCl).
Then there are other types which are formed by mixing either:
A non-metal and a metal
or a metal and an acid
or acid and base
Generally there are different types of salt based on their location, for example natural salt: found in food
Sea salt: found in sea
Rock salt: Huge crystals of salts forming rocks
This is interesting to know that salts exist in all colours (like Nickel chloride is green WOW..), all taste (even sweet! ), and different odors (smell like vinegar).
