The "saponification value " of an oil or fat is measured in term of

Options

A. `NH_(4)OH`
B. `NaOH`
C. `KOH`
D. `C_(6)H_(5)OH`

Explanation

To answer the question regarding the "saponification value" of an oil or fat, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Saponification Value**:
- The saponification value is a measure that indicates how much alkali (in this case, potassium hydroxide) is needed to convert a fat or oil into soap.

2. **Definition of Saponification Value**:
- The saponification value is defined as the number of milligrams of potassium hydroxide (KOH) required to saponify one gram of fat or oil.

3. **Measurement Units**:
- The saponification value is expressed in terms of milligrams of potassium hydroxide per gram of fat or oil.

4. **Conclusion**:
- Therefore, the saponification value of an oil or fat is measured in terms of potassium hydroxide (KOH).

### Final Answer:
The "saponification value" of an oil or fat is measured in terms of **potassium hydroxide (KOH)**.
