Salts also produced from neutralization or titration reaction between acids and alkalis/bases:
Thousands of salts exist naturally in earth.
For example salts like sodium chloride, magnesium chloride, magnesium sulfate, sodium chloride, and sodium bromide exist in sea water.
While salts like calcium fluoride, magnesium sulfate, and lead (II) sulfide exist as mineral in earth crust.
Salts that not exist naturally can be made and produced through chemical method in chemical industry.
