2. WHAT IS AMMONIUM CERIUM SULFATE?
Ammonium cerium sulfate is an inorganic salt composed of cerium(IV), ammonium, and sulfate ions. It appears as light yellow-orange crystals and is soluble in water. Its most important property is being a strong oxidizing agent. Due to this property, it is used as a standard reagent in cerimetry titrations in analytical chemistry, as an oxidizing agent in organic synthesis, and as a catalyst precursor in polymerization reactions. It is sensitive to moisture and light, thus requiring special packaging and storage conditions.

Structure Formula:
(NH₄)₄ [Ce(SO₄)₄] · 2H₂O
Ionic Structure:
-
Cerium(IV) ion: Ce⁴⁺
-
Ammonium ion: NH₄⁺
-
Sulfate ion: SO₄²⁻
-
Water of crystallization: 2H₂O
Redox Reaction (Cerimetry):
Ce⁴⁺ + e⁻ → Ce³⁺
This reaction forms the basis of cerimetric titrations in analytical chemistry. The Ce⁴⁺ ion is reduced to Ce³⁺ by accepting one electron, during which a color change is observed.
