SO₂ Scrubbing System. The CANSOLV SO 2 Scrubbing System uses a tailored amine-based absorbent for regenerable SO 2 capture. Rigorous emissions limits can be met (in many conditions down to 20 ppm) while delivering a useful SO 2 by-product gas stream (rather than a waste stream), typically converted to salable sulfur, sulfuric acid or liquid SO 2.

Water does ionise in solution, forming H + and OH – ions, but as you'll discover post-GCSE, its ionisation is negligible compared to other ionic substances. Don't ionise polyatomic ions! Whilst sulfuric acid (H 2 SO 4) ionises to form sulfate ions (SO 4 2-), you can't ionise sulfate ions any further.
