How to Make a Sodium Chloride Solution

A solution of sodium chloride -- better known as table salt -- and water is known as a saline solution; there are many reasons why you would need one. For example, a normal saline solution, which is one that matches the salinity of the body, is the best one for making a dental rinse or flushing out the eyes.
