When copper ore is mixed with silica in a reverberatory furnace, copper matte is produced. The copper matter contains__________

Options

A. sulphide of copper (II) and iron (II)
B. sulphide of copper (II) and iron (III)
C. sulphide of copper (I) and iron (II)
D. sulphide of copper (II) and iron (I)

Explanation

To answer the question, "When copper ore is mixed with silica in a reverberatory furnace, copper matte is produced. The copper matte contains__________", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Copper Matte**:
- Copper matte is a product formed during the extraction of copper from its ore. It is produced when copper ore is heated with silica in a reverberatory furnace.

2. **Identifying the Components of Copper Matte**:
- Copper matte primarily consists of two compounds: copper(I) sulfide (Cu₂S) and iron(II) sulfide (FeS).

3. **Analyzing the Options**:
- The options provided are:
1. Sulphide of copper(II) and iron(II)
2. Sulphide of copper(II) and iron(III)
3. Sulphide of copper(I) and iron(II)
4. Sulphide of copper(II) and iron(I)
- From our understanding, we know that copper in copper matte is in the +1 oxidation state (Cu₂S) and iron is in the +2 oxidation state (FeS).

4. **Selecting the Correct Option**:
- Based on the components identified, the correct answer is option 3: sulphide of copper(I) and iron(II).

### Final Answer:
The copper matte contains **sulphide of copper(I) and iron(II)**.
