The correct Answer is:
To determine which of the given sulphides is not black in color, we need to analyze each option: 1. **Nickel Sulphide (NiS)**: Nickel sulphide is known to be black in color. 2. **Copper Sulphide (CuS)**: Copper sulphide is also black in color. 3. **Cobalt Sulphide (CoS)**: Cobalt sulphide is typically described as black or dark in color, though it may appear slightly lighter than pure black. 4. **Cadmium Sulphide (CdS)**: Cadmium sulphide is known to be yellow in color, which distinguishes it from the other options. Based on this analysis, the sulphide that is not black in color is **Cadmium Sulphide (CdS)**. ### Final Answer: The sulphide that is not black in color is **Cadmium Sulphide (CdS)**. ---
