To complete the table for perbromic acid and telluric acid, we need to determine their formulas, corresponding anion names, and the formulas for the anions involved. Based on the information provided and standard naming conventions for acids and their anions, here’s the breakdown:
1. Perbromic Acid
- Acid Formula: HBrO₄
- Anion Name: Perbromate
- Anion Formula: BrO₄⁻
Explanation:
Perbromic acid is a strong acid that contains the bromine element in its highest oxidation state (+7). The anion, when the hydrogen ion (H⁺) is removed, forms the perbromate ion (BrO₄⁻), which is a polyatomic ion. This name follows a pattern where the acid with the highest oxidation state of an element is named with the prefix “per-” and the “-ic” suffix, indicating the presence of oxygen in its highest form.
2. Telluric Acid
- Acid Formula: H₂TeO₃
- Anion Name: Tellurite
- Anion Formula: TeO₃²⁻
Explanation:
Telluric acid is formed by the combination of hydrogen ions (H⁺) with the tellurium-based species. The acid formula H₂TeO₃ indicates that telluric acid contains tellurium in the +4 oxidation state. When this acid dissociates in solution, it releases H⁺ ions, leaving behind the tellurite ion (TeO₃²⁻). The suffix “-ite” is used to name the ion when the element is in a lower oxidation state (compared to the “-ate” form, which would indicate a higher oxidation state).
The naming of acids and their corresponding anions follows the general rules for oxoacids:
- If the central atom is in a high oxidation state, the acid name ends in “-ic” and the corresponding anion name ends in “-ate” (e.g., perbromic acid and perbromate ion).
- If the central atom is in a lower oxidation state, the acid name ends in “-ous” and the corresponding anion name ends in “-ite” (e.g., telluric acid and tellurite ion).
Conclusion:
- Perbromic acid dissociates into H⁺ and perbromate (BrO₄⁻) ions.
- Telluric acid dissociates into H⁺ and tellurite (TeO₃²⁻) ions.
