![### Chemical Reaction: Organosulfur Compound with Lead (II) Ion
**Reaction Equation:**
\[ 2\text{CH}_3\text{CH}_2\text{SH} + \text{Pb}^{2+} \rightarrow \]
This reaction illustrates the combination of an organosulfur compound, specifically ethanethiol (ethyl mercaptan), with a lead (II) ion. The formula for ethanethiol is \(\text{CH}_3\text{CH}_2\text{SH}\), and lead (II) ion is denoted as \(\text{Pb}^{2+}\).
### Explanation of the Equation Components:
1. **Ethanethiol (\( \text{CH}_3\text{CH}_2\text{SH} \))**:
- This is an organosulfur compound containing a thiol (sulfhydryl) group. The thiol group is represented by \( \text{SH} \).
- The ethyl group is \( \text{CH}_3\text{CH}_2 \).
- Ethanethiol contributes two molecules (\( 2 \text{CH}_3\text{CH}_2\text{SH} \)) to this reaction equation.
2. **Lead (II) Ion (\( \text{Pb}^{2+} \))**:
- This ion represents lead in a +2 oxidation state, commonly found in compounds such as lead acetate or lead chloride in aqueous solution.
### Arrow and Placeholder:
- The arrow (→) signifies the direction of the chemical reaction, indicating the formation of products from the reactants.
- The placeholder (\_\_\_\_\_\_) represents the products that will form as a result of this reaction, which are not specified in the diagram.
### Potential Products:
- Although not shown in the image, reactions of thiols with metal ions like \( \text{Pb}^{2+} \) typically result in the formation of metal-thiolate complexes. For example, lead thiolate (\(\text{Pb}(\text{SCH}_2\text{CH}_3)_2\)) could potentially be the product.
### Applications and Relevance:
- Such reactions are significant in environmental chemistry, toxicology, and materials science, where understanding the interaction between organosulfur compounds and heavy metals is essential for applications like pollution mitigation and metal recovery processes.
