telluric acid
HBrO3
chloride ion
S2-
The Correct Answer and Explanation is :
Let’s break down the components of the table and explain each term involved in detail.
- Telluric Acid: The name tells us that this is an acid containing tellurium (Te). In its most common form, telluric acid has the formula H6TeO6. It’s a strong, oxidizing acid, typically found as a white crystalline solid in its hydrated form. It forms salts called tellurates when combined with a base.
- HBrO3: This is Bromic Acid. The presence of bromine (Br) suggests that this acid is derived from bromine. Bromic acid has the formula HBrO3, and it belongs to the category of oxoacids, meaning it contains oxygen. The number of oxygen atoms indicates the oxidation state of the central element, bromine in this case, which is +5.
- Chloride Ion: The chloride ion is simply the ion derived from chlorine. It is a negatively charged ion (anion) with the formula Cl-. This is one of the most common halide ions and is present in many salts, such as sodium chloride (NaCl).
- S2-: This is the Sulfide Ion, an anion derived from sulfur. The formula S2- indicates that it has a charge of -2, meaning it has gained two electrons. Sulfide ions are often found in salts like iron sulfide (FeS), where sulfur combines with metals.
Now, to complete the table:
| Acid Name | Acid Formula | Anion Name | Anion Formula |
|---|---|---|---|
| Telluric Acid | H6TeO6 | Tellurate Ion | TeO6^2- |
| Bromic Acid | HBrO3 | Bromate Ion | BrO3^- |
| Hydrochloric Acid | HCl | Chloride Ion | Cl^- |
| Hydrogen Sulfide | H2S | Sulfide Ion | S^2- |
Explanation:
- Telluric Acid is an acid containing tellurium (Te), and the anion derived from it is the tellurate ion (TeO6^2-).
- Bromic Acid (HBrO3) is part of the group of oxoacids, where bromine forms the bromate anion (BrO3^-).
- Hydrochloric Acid (HCl) is a classic strong acid that dissociates into the chloride ion (Cl^-), which is one of the simplest halide ions.
- Hydrogen Sulfide (H2S) dissociates to form the sulfide ion (S^2-), which is commonly encountered in geological and biological processes.
These acids and their corresponding anions are important in chemistry because of their varied uses and roles in different chemical reactions, especially in fields like biochemistry, industrial chemistry, and environmental science.
