The electrolyte for the electroplating an article with silver is

Options

A. Silver nitrate solution
B. Silver cyanide solution
C. Sodium argentocyanide solutions
D. Silver acetate

Answer

To determine the correct electrolyte for electroplating an article with silver, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electroplating**:
- Electroplating is a process that uses electrical current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode. The metal to be deposited is usually a noble metal, such as silver.

2. **Identifying Common Electrolytes for Silver Electroplating**:
- Common electrolytes for silver electroplating include silver nitrate (AgNO3), silver cyanide (AgCN), sodium argentocyanide (Na[Ag(CN)2]), and silver acetate (AgC2H3O2).

3. **Analyzing the Options**:
- **Silver Nitrate**: A common electrolyte, but it may not provide an even deposition of silver.
- **Silver Nitrate Solution**: Similar to silver nitrate, it may not be the best choice for even deposition.
- **Silver Cyanide Solution**: This can be used, but it is less common compared to sodium argentocyanide.
- **Sodium Argentocyanide Solution**: This is known for providing a more uniform deposition of silver due to the slower migration of Ag+ ions.
- **Silver Acetate**: This is not commonly used for electroplating silver.

4. **Selecting the Best Option**:
- Among the options, sodium argentocyanide solution is preferred for electroplating silver because it allows for a more controlled and even deposition of silver on the article.

5. **Conclusion**:
- The best electrolyte for electroplating an article with silver is **sodium argentocyanide solution**.

### Final Answer:
The electrolyte for the electroplating an article with silver is **sodium argentocyanide solution**.
