Which of the following metal is extracted by amalgamation process?

Options

A. Tin
B. Silver
C. Copper
D. Zinc

Answer

To determine which metal is extracted by the amalgamation process, we can follow these steps:

### Step 1: Understand the Amalgamation Process
The amalgamation process is a method used to extract certain metals, particularly precious metals, by using mercury to form an amalgam. This process is primarily used for metals like gold and silver.

**Hint:** Remember that amalgamation involves the use of mercury to extract metals.

### Step 2: Identify the Metals Commonly Extracted by Amalgamation
Among the metals, silver (Ag) and gold (Au) are the most commonly extracted using the amalgamation process.

**Hint:** Focus on precious metals when considering amalgamation.

### Step 3: Analyze the Given Chemical Reactions
The transcript mentions a series of chemical reactions related to the extraction of silver:
1. \( \text{Cu}_2\text{Cl}_2 + \text{Ag}_2\text{S} \rightarrow \text{Cu}_2\text{S} + 2\text{AgCl} \)
2. \( 2\text{AgCl} + 2\text{Hg} \rightarrow \text{Hg}_2\text{Cl}_2 + 2\text{Ag} \)
3. \( \text{AgCl} + \text{Hg} \rightarrow \text{Ag} + \text{HgCl} \)

These reactions show how silver is extracted from its compounds using mercury.

**Hint:** Look for the presence of silver in the reactions to confirm its extraction.

### Step 4: Conclusion
Based on the information provided, the metal that is extracted by the amalgamation process is silver (Ag).

**Final Answer:** Silver (Ag) is extracted by the amalgamation process.
