1. What is Iodine Value?

Iodine Value (IV) is a measure of the degree of unsaturation in fats and oils. It represents the number of grams of iodine absorbed by 100 grams of fat, indicating the amount of double bonds present in the fatty acid chains.

2. How Does the Calculator Work?

The calculator uses the Iodine Value equation:

\[ IV = \frac{(B - S) \times N \times 12.69}{W} \]

Where:

\( B \) — Blank titer (ml)
\( S \) — Sample titer (ml)
\( N \) — Normality of sodium thiosulfate solution (N)
\( W \) — Weight of sample (g)
12.69 — Conversion factor (equivalent weight of iodine × 100)

Explanation: The equation calculates the amount of iodine absorbed by the fat sample, which correlates with the degree of unsaturation in the fatty acids.

3. Importance of Iodine Value Calculation

Details: Iodine Value is crucial for determining the quality and stability of fats and oils. Higher values indicate more unsaturated fats, which are more prone to oxidation but may have different nutritional properties.

4. Using the Calculator

Tips: Enter blank titer and sample titer in ml, normality in N, and sample weight in grams. All values must be positive numbers with appropriate precision.

5. Frequently Asked Questions (FAQ)

Q1: What does a high Iodine Value indicate?
A: A high IV indicates a higher degree of unsaturation, meaning the fat contains more double bonds and is more liquid at room temperature.

Q2: What are typical Iodine Value ranges for common oils?
A: Olive oil: 75-94, Coconut oil: 6-11, Soybean oil: 120-143, Linseed oil: 170-204.

Q3: Why is the blank titration necessary?
A: The blank titration accounts for any iodine consumed by reagents or environmental factors, ensuring accurate measurement of iodine absorbed by the sample.

Q4: What is the significance of the 12.69 factor?
A: This factor converts the titration results to grams of iodine per 100 grams of sample, where 12.69 represents (126.9/100) × 10 (equivalent weight of iodine × 100 ÷ 1000 for ml to g conversion).

Q5: Can this calculator be used for all types of fats?
A: Yes, the iodine value calculation is applicable to all fats and oils, though sample preparation methods may vary depending on the specific material.
