Sodium Chloride Calculator ( Salt )

A colorless or white crystalline compound, NaCl, used in the manufacture of chemicals and as a food preservative and seasoning is called as Sodium Chloride. It is a common table salt, a necessary constituent of the body and therefore of the diet, involved in maintaining osmotic tension of blood and tissues; uses include replenishment of electrolytes in the body, irrigation of wounds and body cavities, enema, inhaled mucolytic, topical osmotic ophthalmic agent, and preparation of pharmaceuticals.

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.

Example:
Calculate the percentage of chloride as sodium chloride by the given details.
Volume of silver nitrate = 250
Volume of kscn = 30
Sample weight = 15

Solution:
Apply Formula:
Percentage of chloride as Sodium Chloride = (Weight of silica crucible with contents before ashing * weight of silica crucible with contents after ashing/weight of sample*100)

Percentage of chloride as sodium chloride = 857.26666666
