Identify the correct statement (s) in reflection to the following reaction :
`Zn+2HClrarr ZnCl_2+H_2`

Options

A. Zinc is acting as an oxidant
B. Chlorine is acting as a reluctant
C. Hydrogen ion is acting as an oxidant
D. Zinc is acting as a reluctant

Explanation

To solve the question regarding the reaction \( \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 \), we will follow these steps:

### Step 1: Write the balanced chemical equation
The given reaction is already balanced:
\[ \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 \]

### Step 2: Determine oxidation states of each element
- **Zinc (Zn)**: In its elemental form, the oxidation state is \( 0 \).
- **Hydrogen in HCl**: The oxidation state of hydrogen is \( +1 \).
- **Chlorine in HCl**: The oxidation state of chlorine is \( -1 \).
- **Zinc in ZnCl2**: Let the oxidation state of Zn be \( x \). The equation for ZnCl2 is:
\[ x + 2(-1) = 0 \implies x - 2 = 0 \implies x = +2 \]
- **Hydrogen in H2**: In its elemental form, the oxidation state is \( 0 \).

### Step 3: Identify the changes in oxidation states
- **Zinc (Zn)**: Changes from \( 0 \) to \( +2 \) (oxidation).
- **Hydrogen ions (H+)**: Changes from \( +1 \) to \( 0 \) (reduction).

### Step 4: Classify the species
- **Oxidation**: The species that loses electrons (increases oxidation state) is the reducing agent. Here, zinc is oxidized, so it acts as a **reductant**.
- **Reduction**: The species that gains electrons (decreases oxidation state) is the oxidizing agent. Here, hydrogen ions are reduced, so they act as an **oxidant**.

### Step 5: Conclusion
From the analysis:
- Zinc (Zn) is acting as a **reductant**.
- Hydrogen ions (H+) are acting as an **oxidant**.

### Step 6: Identify the correct statements
Based on the classifications:
- **Option 3**: Hydrogen ions (H+) are acting as an oxidant. **(Correct)**
- **Option 4**: Zinc (Zn) is acting as a reductant. **(Correct)**

Thus, the correct statements in reflection to the reaction are:
- **Option 3 and Option 4 are correct.**
