The _________colour is obtained on silver is due to the formation of silver sulphide.

Options

A. Black
B. Green
C. Brown
D. Reddish - brown

Answer

To solve the question, we need to identify the color that appears on silver due to the formation of silver sulfide. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Reaction
- Silver (Ag) can react with sulfur (S) to form silver sulfide (Ag2S). This is a chemical reaction where silver combines with sulfur.

### Step 2: Identify the Product
- The product of this reaction is silver sulfide, which has the chemical formula Ag2S.

### Step 3: Determine the Color of Silver Sulfide
- Silver sulfide is known to be a black dense solid. This means that when silver reacts with sulfur and forms silver sulfide, the resulting color on the surface of the silver will be black.

### Step 4: Fill in the Blank
- The blank in the question can be filled with "black" since the color obtained on silver due to the formation of silver sulfide is black.

### Final Answer
- The black color is obtained on silver due to the formation of silver sulfide.
