If the soap is fully and completely water soluble, its chloride content can be precipitated by adding silver nitrate solution to the soap solution, and the amount of silver chloride solution used until precipitation ceases measures the content of sodium originally in the solution. There are also many other analytical methods available.

Why does NaCl heelp to precipitate the soap from aqueous soltion?
It depends on the salt. A salt of calcium, magnesium, or iron will form an insoluble compound that will precipitate with a soap molecule that is known as soap scum. Here is a typical reaction: Ca2+(aq) + 2C17H35COO-(aq) ==> (C17H35COO-)2Ca2+(s) Sodium chloride will not form a precipitate with soap as long as the soap is a carboxylate.
