Frequently Asked Questions
As with many strong acids, it can be corrosive. Its specific hazards depend on concentration, but it is not a common laboratory chemical.
They are different sulfur oxoacids. Dithionic acid is H₂S₂O₆, where sulfur has an oxidation state of +5. Dithionous acid is H₂S₂O₄, where sulfur has an oxidation state of +3.
No. It is a highly specialised technical term only relevant to specific scientific disciplines.
In technical contexts, it can shorthand for 'dithionate' (the salt), e.g., 'potassium dithionic'. However, to avoid ambiguity, 'dithionate' is preferred for salts, and 'dithionic acid' for the acid itself.
