Heat of neutralization of the acid-base reaction is -`57.32` KJ for :

Options

A. HCOOH +KOH
B. `CH_(3)COOH + NaOH`
C. `HNO_(3) + LiOH`
D. `HCl + NaOH`

Answer

To determine the heat of neutralization for the given acid-base reactions, we need to understand the concept of heat of neutralization and identify the strong acids and strong bases involved in the reactions.

### Step-by-Step Solution:

1. **Understanding Heat of Neutralization**:
- The heat of neutralization is defined as the heat change when one equivalent of an acid reacts with one equivalent of a base to form water and a salt.
- For strong acids and strong bases, this value is typically around -57.32 kJ/mol. The negative sign indicates that the reaction is exothermic, meaning it releases heat.

2. **Identifying Strong Acids and Strong Bases**:
- Strong acids include: HCl, HNO3, H2SO4, etc.
- Strong bases include: NaOH, KOH, LiOH, etc.
- In this question, we need to identify which combinations of acids and bases are strong.

3. **Analyzing Given Options**:
- Let's analyze the combinations:
- **Option A**: HNO3 + LiOH
- HNO3 is a strong acid, and LiOH is a strong base. Therefore, this combination will have a heat of neutralization of -57.32 kJ.
- **Option B**: HCl + NaOH
- HCl is a strong acid, and NaOH is a strong base. This combination will also have a heat of neutralization of -57.32 kJ.
- **Option C**: (Assuming it contains a weak acid or weak base)
- If one component is weak, the heat of neutralization will not be -57.32 kJ.
- **Option D**: (Assuming it contains a weak acid or weak base)
- Similar to Option C, if one component is weak, the heat of neutralization will not be -57.32 kJ.

4. **Conclusion**:
- The combinations that yield the heat of neutralization of -57.32 kJ are:
- HNO3 + LiOH (strong acid + strong base)
- HCl + NaOH (strong acid + strong base)
- Therefore, the correct options are those that consist of strong acids and strong bases.

### Final Answer:
The heat of neutralization of -57.32 kJ is applicable for the reactions involving strong acids and strong bases, such as HNO3 + LiOH and HCl + NaOH.
