Classify each of the following unbalanced half-reactions as either an oxidation or a reduction. (d) SbCl4-(aq) → SbCl6-(aq)

검증된 단계별 안내
1
Identify the oxidation states of the central atom (Sb) in both the reactant and the product.
In SbCl_4^- (aq), determine the oxidation state of Sb by considering the oxidation state of Cl as -1.
In SbCl_6^- (aq), determine the oxidation state of Sb by considering the oxidation state of Cl as -1.
Compare the oxidation states of Sb in the reactant and product to determine if it has increased or decreased.
If the oxidation state of Sb increases, it is an oxidation reaction; if it decreases, it is a reduction reaction.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Oxidation and Reduction

Oxidation and reduction are chemical processes that involve the transfer of electrons between species. Oxidation refers to the loss of electrons, resulting in an increase in oxidation state, while reduction involves the gain of electrons, leading to a decrease in oxidation state. These processes are always coupled, meaning that when one species is oxidized, another must be reduced.

Oxidation and Reduction Reactions

Oxidation States

Oxidation states (or oxidation numbers) are a way to keep track of electron transfer in redox reactions. Each element in a compound is assigned an oxidation state based on its electron configuration and bonding. Understanding how to assign oxidation states is crucial for identifying which species is oxidized and which is reduced in a half-reaction.

Oxidation Numbers

Half-Reactions

Half-reactions are equations that show either the oxidation or reduction process separately. They are useful for balancing redox reactions and understanding the electron transfer involved. In the context of the given question, analyzing the half-reaction allows us to determine whether the species is gaining or losing electrons, thus classifying it as oxidation or reduction.

The concentration of an aqueous solution of NaOCl (sodium hypochlorite; the active ingredient in household bleach) can be determined by a redox titration with iodide ion in acidic solution:

Assume that the blue spheres in the buret represent I-ions, the red spheres in the flask represent OCl-ions, the con-centration of the I-ions in the buret is 0.120 M, and the volumes in the buret and the flask are identical. What is the concentration of NaOCl in the flask? What percentage of the I-solution in the buret must be added to the flask to react with all the OCl-ions?
