Which of the following statemetns about tailing of `Hg` is`//`are correct?

Options

A. It is due to `Hg_(2)O`.
B. It is due to `HgO`
C. It is removed by `H_(2)O_(2)`
D. It is removed by `O_(3)`

Explanation

To solve the question regarding the statements about the tailing of mercury (Hg), we will analyze the information provided in the video transcript step by step.

### Step 1: Understanding Tailing of Mercury
Tailing of mercury refers to the phenomenon where mercury loses its miscibility and adheres to glass surfaces. This occurs due to the formation of mercury(I) oxide (Hg2O) when mercury is oxidized.

**Hint:** Consider what happens to mercury when it undergoes oxidation and how it interacts with glass surfaces.

### Step 2: Oxidation of Mercury
When mercury (Hg) is oxidized, it forms mercury(I) ions (Hg2+). The oxidation can occur through reactions with oxidizing agents such as ozone (O3).

**Hint:** Recall the oxidation states of mercury and how it can change during chemical reactions.

### Step 3: Chemical Reactions Involved
The video transcript mentions the following reactions:
1. \( 2 \text{Hg} + \text{O}_3 \rightarrow \text{Hg}_2\text{O} + \text{O}_2 \)
2. \( \text{Hg}_2\text{O} + \text{H}_2\text{O}_2 \rightarrow 2 \text{Hg} + \text{H}_2\text{O} + \text{O}_2 \)

From these reactions, we can conclude that:
- The formation of Hg2O is a key factor in the tailing of mercury.
- The removal of this tailing can occur through the action of hydrogen peroxide (H2O2).

**Hint:** Identify the role of each reactant and product in the reactions provided.

### Step 4: Evaluating the Statements
Now, we evaluate the statements regarding the tailing of mercury:
1. Tailing is due to the formation of Hg2O (Correct).
2. Tailing is removed by H2O2 (Correct).
3. Tailing is removed by O3 (Incorrect).

Based on our analysis, the correct statements are:
- Tailing of Hg is due to Hg2O.
- Tailing of Hg is removed by H2O2.

**Hint:** Cross-check each statement with the reactions and the explanations given in the video.

### Conclusion
The correct options regarding the statements about the tailing of mercury are:
- Option A: Tailing of Hg is due to Hg2O (Correct).
- Option C: Tailing of Hg is removed by H2O2 (Correct).

### Final Answer
The correct statements about the tailing of mercury (Hg) are options A and C.
