As sulfur dioxide is an ,acidic, gas it will need to be neutralised before disposal. To do this an alkaline-based sorbent is used to bring the pH level of the sulfur dioxide gas closer to neutral. Scrubber systems are one of the most efficient ways of reducing sulfur dioxide emissions caused by industrial combustion, and a classic example of an acid-base chemical reaction performed on an industrial scale.

The weaker the ,acid, HA, the more readily will reaction take place, thus gobbling up A – ions. If an excess of H + is made available by addition of a strong ,acid,, even more A – ions will be consumed, eventually reversing reaction , causing the solid to dissolve. In , for example, sulfate ions react with calcium ions to form insoluble CaSO 4.
