This chemical equation has the general form of an exchange reaction: AC + BD → ADinsoluble + BC (7.8.1) (7.8.1) AC + BD → AD i n s o l u b l e + BC. Thus precipitation reactions are a subclass of exchange reactions that occur between ionic compounds when one of the products is insoluble. Because both components of each …
The scrubbing of hydrogen sulfide (H 2S) using sodium hydroxide (NaOH) solution is established technology, and has been applied in a variety of industries. Since this process uses a solvent which cannot be easily regenerated, caustic scrubbers are most often applied in situations where small volumes of H 2S need to be removed. The removal of ...
