How to Calculate Iodine Value
Iodine value, a measure of the average molecular weight of the fatty acids in a fat or oil, is crucial in food, pharmaceutical, and chemical industries. This calculator helps you determine the iodine value of various substances.
- Select the substance from the dropdown.
- Enter the amount in grams.
- Click ‘Calculate’.
The iodine value (IV) is calculated using the formula:
IV = (1000 * B * 126.9) / A
where A is the amount of substance in grams, and B is the grams of iodine consumed by 100g of the substance.
Case Studies
- Coconut Oil: Amount = 100g, B = 16.7. IV = 10.02
- Olive Oil: Amount = 150g, B = 89.5. IV = 60.33
- Palm Oil: Amount = 75g, B = 56.8. IV = 42.6
Comparison Tables
| Substance | Amount (g) | B (g iodine/100g) | Iodine Value |
|---|---|---|---|
| Coconut Oil | 100 | 16.7 | 10.02 |
Expert Tips
- Always use fresh, high-quality samples for accurate results.
- Ensure the sample is completely dry before testing.
- Store samples in a cool, dry place away from light and heat.
