Sample Volume for Iodine Value - (Measured in Cubic Meter) - Sample Volume for Iodine Value is volume in ml of standard sodium thiosulphate solution required for the sample.
Solution Normality for Iodine Value - (Measured in Mole per Cubic Meter) - Solution Normality for Iodine Value is normality of the standard sodium thiosulphate solution.
Sample Weight - (Measured in Kilogram) - Sample Weight is weight of plant material taken.

STEP 1: Convert Input(s) to Base Unit

Blank Volume for Iodine Value: 120 Milliliter --> 0.00012 Cubic Meter (Check conversion here)
Sample Volume for Iodine Value: 90 Milliliter --> 9E-05 Cubic Meter (Check conversion here)
Solution Normality for Iodine Value: 3.4 Equivalents per Liter --> 3400 Mole per Cubic Meter (Check conversion here)
Sample Weight: 150 Gram --> 0.15 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

IV = 1.69*(B_i-S_i)*N_i/W --> 1.69*(0.00012-9E-05)*3400/0.15

Evaluating ... ...

IV = 1.1492

STEP 3: Convert Result to Output's Unit

1.1492 --> No Conversion Required

FINAL ANSWER

1.1492 <-- Iodine Value

What is the principle of iodine value?

The oil/fat sample taken in carbon-tetrachloride is treated with a known excess of iodine monochloride solution in glacial acetic acid (Wij’s solution). The excess of iodine monochloride is treated with potassium iodide and the liberated iodine estimated by titration with sodium thiosulphate solution.

How to Calculate Iodine Value?

Iodine Value calculator uses Iodine Value = 1.69*(Blank Volume for Iodine Value-Sample Volume for Iodine Value)*Solution Normality for Iodine Value/Sample Weight to calculate 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.
