The chemical name for the acid with the chemical formula HIO₄ is Periodic acid. There are rules applied to polyatomic oxyanions like iodate. IO⁻ is hypoiodite, IO₂⁻ is iodite, IO₃⁻ is iodate, and IO₄⁻ is periodate. When they gain an H⁺ atom and become an acid, drop the - ite or - ate suffice and replace with - ic acid.
