Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H 3 O +) and hydrogen sulfate ions (HSO 4 −).In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO 4 2−).In addition to being an oxidizing agent, reacting readily at high temperatures with …

Introduction. The Absorbing Acid System absorbs the sulphur xide (SO3) that is formed in the converter to produce sulphuric acid.The reason for absorbing the SO3 is to achieve the desired production of sulphuric acid and to avoid environmental problems that would result if the SO3 were allowed to exscape to the environment. Efficiently absorbing the …

The chemistry of the leaching process revolves around oxidation of the uranium compounds, which is typically achieved using manganese dioxide (MnO 2), sodium chlorate (NaClO 3), and Fe(II) salts. Equation (ref{23.3.1a})- (ref{23.3.1c}) shows a typical reaction pathway for the acid leaching process using sulfuric acid.
