Question

Name the anion obtained by removing one oxygen atom from the perbromate ion, BrO₄(⁻)

Answer 1

The anion formed by removing one oxygen atom from the perbromate ion (BrO⁻) is the bromate ion (BrO₃⁻).

Step-by-step explanation:

The anion obtained by removing one oxygen atom from the perbromate ion, BrO4⁻, is called the bromate ion, BrO3⁻.

Following the naming pattern for oxyanions of halogens:

• A halogen with four oxygen atoms is named with the prefix "per-" and the ending "-ate". Example: BrO4⁻ is perbromate.
• Removing one oxygen from the perbromate ion results in a halogen with three oxygen atoms. This is named simply with the halogen and the ending "-ate". Example: BrO3⁻ is bromate.

Thus, the perbromate ion BrO4⁻ becomes the bromate ion BrO3⁻ when one oxygen atom is removed.
