problem
Compound X contains element E. The mass percentage of E in X is 74.65%. X can be formed from a common binary oxide of E by boiling it with bromine (Br2) in a sodium hydroxide (NaOH) solution. Sodium bromide (NaBr) and water (H2O) are formed as side products. After this reaction, the oxidation state of E increases by 2.
X is a strong oxidising agent, oxidising manganese(II) ions (2+) in a hot solution of sulfuric acid (H2SO4) and nitric acid (HNO3) to permanganate ions (-).
Identify X.
