Example: HOCl and WaterSame number of atoms per moleculeChlorine substituted for hydrogenChlorine is more electronegativetable 3.3 p19Dissociation of both is likelyHOHOHCl
DissociationBoth molecules will be impacted by pHChlorine as an ion (hypochlorous acid) looks less like hydroxide than HOCl does to H2OOHCl-+HOH-+OHClHOH
