Sulfuric acid is typically used due to the solubility of uranyl sulfate complexes.  The reaction is typically performed at slightly elevated temperatures (~60C) and can often release H 2, H 2 S, and CO 2 gases during the process.  The uranium, which typically begins in the tetravalent state, goes through a series of reactions, ...
Sulfuric acid is the strongest commercially important acid — an oxyacid —, which is a powerful dehydrating agent too. Barium chloride and sulfuric acid, if reacted, produce a waterinsoluble solid, barium sulfate, plus hydrochloric acid. The reaction of these two substances is written BaCl 2 + H 2 SO 4 → BaSO 4 + 2 HCl.
