What is NaCl?
Sodium chloride (NaCl), a necessary substance for our bodies, usually referred to as salt.
Since salt is an inorganic substance, it does not originate from biological things. It is created when sodium chloride and chloride combine to form white, crystalline cubes.
Although salt is essential for your body to operate, too little or too much salt can be bad for your health.
While salt is widely used in cooking, it is also a component of some meals and cleaning products. Your doctor or nurse will often administer sodium chloride as an injection in medical situations.
