It is a weak one. It is not a strong electrolyte because it has one less oxygen than H2SO4, by comparison. that difference of one oxygen atom means that less electron density is pulled away from the O-H bonds in the compound, and as a result, the O-H bond in H2S03 is stronger than in H2SO4, and so it is less likely to dissociate into H+ and HSO3- 1. Strong acids are listed at the top left hand corner of the table and have Ka values >1 2.
