Cerium shows +4 oxidation state
WebCerium (Ce) shows +4 oxidation state as in this it acquires stable noble gas configuration but it is a strong oxidising agent and oxidises to Ce3+ (common) state. Its E° value for Ce4+/Ce3+ is 1.74 V. It oxidises water but the rate of reaction is slow and thus can be studied in detailed and analysed. Hence Ce acquires great use in analytical reagents.
