What’s the formula for hypsulfite

Question

about Polyatomics an elements compounds an formulas

Answer 1

This is about naming oxyanions. Start with -ate; remove one O to get -ite; remove another O to get hypo-ite

To deduce the formula for the hyposulfite anion, start with sulfate, SO₄^2-

Remove one oxygen to get SO₃^2- which is sulfite

Remove one more oxygen to get SO₂^2- which is hyposulfite

(NOTE: hyposulfite/hyposulfurous acid probably don't actually exist)
