The given reaction `NaOH + HC1 to NaC1 + H_(2)O` is na example of

Options

A. neutralisation reaction
B. double displacement reaction
C. exothermic reaction
D. all of these

Answer

To determine the type of reaction represented by the equation `NaOH + HCl → NaCl + H₂O`, we can analyze the components and the nature of the reaction step by step.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactants in the reaction are Sodium Hydroxide (NaOH) and Hydrochloric Acid (HCl).
- The products formed are Sodium Chloride (NaCl) and Water (H₂O).

2. **Classify the Reaction**:
- This reaction involves an acid (HCl) and a base (NaOH). When an acid reacts with a base, it typically produces a salt and water. This is the definition of a neutralization reaction.

3. **Check for Double Displacement**:
- In this reaction, the hydroxide ion (OH⁻) from NaOH is replaced by the chloride ion (Cl⁻) from HCl.
- Similarly, the chloride ion (Cl⁻) is replaced by the hydroxide ion (OH⁻) to form water. This exchange of ions indicates that the reaction is also a double displacement reaction.

4. **Exothermic Nature of the Reaction**:
- Neutralization reactions generally release heat. In this case, when NaOH reacts with HCl, heat is released, making it an exothermic reaction.

5. **Conclusion**:
- Since the reaction is a neutralization reaction, a double displacement reaction, and it is exothermic, we can conclude that it falls under all three categories.

### Final Answer:
The given reaction `NaOH + HCl → NaCl + H₂O` is an example of a neutralization reaction, a double displacement reaction, and an exothermic reaction.
