The anion [Ce(NO 3) 6] 2− has T h (idealized O h) molecular symmetry.The CeO 12 core defines an icosahedron. [4]Ce 4+ is a strong one-electron oxidizing agent.In terms of its redox potential (E° ≈ 1.61 V vs. N.H.E.) it is an even stronger oxidizing agent than Cl 2 (E° ≈ 1.36 V).
It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid. KHP is slightly acidic , and it is often used as a primary standard for acid–base titrations because it is solid and air-stable, making it easy to weigh accurately.
