A known excess volume of silver nitrate solution is added to precipitate all chloride as silver chloride. Titrate the excess unreacted silver nitrate with known strength of potassium thio cyanate, kscn using ferric alum as indicator.

The end point is the appearance of reddish tinge on the precipitate (Mohr's method). Thus by this free online chemistry calculator, estimation of chloride as sodiumchloride with kscn as titrate agent is made easy.
