True or False. The formula with charge for arsenate, a polyatomic ion, is AsO₃³⁻.

The same general formula is observed for oxyanions in the same group and is therefore named similarly 

Identify the names of the oxyanions of bromine and iodine BrO₃⁻, BrO₄⁻, IO₃⁻, IO₄⁻

Oxygen and sulfur have a high affinity in chemical reactions with each other. These two elements form a large number of compounds when they react. Sulfur forms many oxyacids that dissociate into their oxyanions in solutions. One of the many sulfur oxyanions is the bisulfite anion. Write a chemical formula for this oxyanion.
