Ammonium sulfate precipitation is a method used to purify proteins by altering their solubility.It is a specific case of a more general technique known as salting out. Ammonium sulfate is commonly used as its solubility is so high that salt solutions with high ionic strength are allowed.his is usually done by adding solid ammonium sulfate, but calculating how much ammonium sulfate to add to a solution at one concentration to achieve a desired higher concentration is tricky, since addition of ammonium sulfate significantly increases the volume of the solution.
The ammonium ion is a positively charged ion or cation and has the chemical formula, NH 4 +. Ammonium salts are commonly used in fertilizers. Examples of compounds containing the ammonium ion include, ammonium nitrate, NH 4 NO 3 and ammonium sulfate, (NH 4) 2 SO 4.All ammonium salts are soluble in water and dissociate or break down to produce aqueous ammonium ions.he ammonium ion is formed by the neutralization of the base ammonia, NH 3 with and acid. NH 3 + HNO 3 4 NO 3. NH 3 + H 2 SO 4 4) 2 SO 4. The ammonium ion has one co-ordinate covalent bond which involves the nitrogen atom donating two electrons in one of the N-H bonds.
