Here is how the Iodine Value equation looks like.

1.1492 = 1.69 \cdot (120 - 90) \cdot \frac{3.4}{150}

1.1492 = 1.69 \cdot (120mL - 90mL) \cdot \frac{3.4Eq/L}{150g}

1.1492 = 1.69 \cdot (120 - 90) \cdot \frac{3.4}{150}

Iodine Value Solution

Follow our step by step solution on how to calculate Iodine Value?

FIRST Step Consider the formula

IV = 1.69 \cdot (B i - S i) \cdot \frac{N i}{W}

Next Step Substitute values of Variables

∴

IV = 1.69 \cdot (120mL - 90mL) \cdot \frac{3.4Eq/L}{150g}

Next Step Convert Units

∴

IV = 1.69 \cdot (0.0001m³ - 9E-5m³) \cdot \frac{3400mol/m³}{0.15kg}

Next Step Prepare to Evaluate

∴

IV = 1.69 \cdot (0.0001 - 9E-5) \cdot \frac{3400}{0.15}

LAST Step Evaluate

∴

IV = 1.1492

How to Evaluate Iodine Value?

Iodine Value evaluator uses Iodine Value = 1.69*(Blank Volume for Iodine Value-Sample Volume for Iodine Value)*Solution Normality for Iodine Value/Sample Weight to evaluate the Iodine Value, The Iodine Value formula is defined as the number of gm of iodine absorbed by 100 g of the oil/fat, when determined by using Wij’s solution. The iodine value is a measure of the amount of unsaturation (number of double bonds) in a fat. Iodine Value is denoted by IV symbol.

How to evaluate Iodine Value using this online evaluator? To use this online evaluator for Iodine Value, enter Blank Volume for Iodine Value (B_i), Sample Volume for Iodine Value (S_i), Solution Normality for Iodine Value (N_i) & Sample Weight (W) and hit the calculate button.

FAQs on Iodine Value

What is the formula to find Iodine Value?

The formula of Iodine Value is expressed as Iodine Value = 1.69*(Blank Volume for Iodine Value-Sample Volume for Iodine Value)*Solution Normality for Iodine Value/Sample Weight. Here is an example- 1.1492 = 1.69*(0.00012-9E-05)*3400/0.15.

How to calculate Iodine Value?

With Blank Volume for Iodine Value (B_i), Sample Volume for Iodine Value (S_i), Solution Normality for Iodine Value (N_i) & Sample Weight (W) we can find Iodine Value using the formula - Iodine Value = 1.69*(Blank Volume for Iodine Value-Sample Volume for Iodine Value)*Solution Normality for Iodine Value/Sample Weight.
