Work Step by Step
1) HBrO₄
The anion is BrO₄⁻, called perbromate.
When hydrogen is added to form the acid, the name ends in “-ic acid.”
HBrO₄ → perbromic acid
2) KIO₃
This is an ionic compound, composed of K⁺ and IO₃⁻ (iodate).
KIO₃ → potassium iodate
3) NaBrO₂
Another ionic compound, with Na⁺ and BrO₂⁻ (bromite).
NaBrO₂ → sodium bromite
4) HIO
The anion here is IO⁻ (hypoiodite).
The acid derived from that anion is named using the “hypo- … -ous acid” pattern.
HIO → hypoiodous acid
