Estimation of chloride as sodiumchloride (NaCl) with KSCN as titrate agent. A known excess volume of silver nitrate (AgNO3) solution is added to precipitate all chloride as silver chloride. Titrate the excess unreacted AgNO3 with known strength of KSCN using ferric alum as indicator. The end point is the appearance of reddish tinge on the precipitate.\r\np: percentage of chloride as sodiumchloride \r\n
