Question

hio₃ spell out the full name of the acid.

Explanation:

To name the acid \( \ce{HIO_3} \), we first identify the anion. The anion here is \( \ce{IO_3^-} \), which is the iodate ion (derived from iodine with oxygen, following the naming for oxyanions: -ate for the common form). For an acid formed from an -ate anion, we use the -ic acid suffix and change the anion name's suffix. So, iodate becomes iodic, and adding hydrogen (as it's an acid), the name is iodic acid.

Answer:

iodic acid
