A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to retain its level of free acid. The heat of reaction keeps reactor temperature at 60 °C.
Ammonium sulfite can be prepared by the reaction of ammonia with sulfur dioxide in aqueous solution: 2 NH 3 + SO 2 + H 2 O → (NH 4) 2 SO 3. Ammonium sulfite is produced in gas scrubbers, now obsolete, consisting of ammonium hydroxide to remove sulfur dioxide from emissions from power plants. The conversion is the basis of the Walther Process.
OK, the theory, dissolving a salt in water can make the resulting solution acidic or basic. When a salt dissolves in water, in general they break op in ions, e.g. a solution of NaCl (tablesalt) in water contains Na + ions and Cl--ions, both by definition in equal quantities, and both hydrated with a certain number of water molecules. Now the ...
Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4 ·Fe(SO 4)·6H 2 O.Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate.
