Here is how the Saponification value equation looks like.

0.187 = 56.11 \cdot (20 - 10) \cdot \frac{0.5}{1.5}

0.187g = 56.11g/mol \cdot (20mL - 10mL) \cdot \frac{0.5}{1.5g}

0.187 = 56.11 \cdot (20 - 10) \cdot \frac{0.5}{1.5}

Saponification value Solution

Follow our step by step solution on how to calculate Saponification value?

FIRST Step Consider the formula

SV = M w \cdot (V b - V a) \cdot \frac{N}{W s}

Next Step Substitute values of Variables

∴

SV = 56.11g/mol \cdot (20mL - 10mL) \cdot \frac{0.5}{1.5g}

Next Step Convert Units

∴

SV = 0.0561kg/mol \cdot (2E-5m³ - 1E-5m³) \cdot \frac{0.5}{0.0015kg}

Next Step Prepare to Evaluate

∴

SV = 0.0561 \cdot (2E-5 - 1E-5) \cdot \frac{0.5}{0.0015}

Next Step Evaluate

∴

SV = 0.000187033333333333kg

Next Step Convert to Output's Unit

∴

SV = 0.187033333333333g

LAST Step Rounding Answer

∴

SV = 0.187g

How to Evaluate Saponification value?

Saponification value evaluator uses Saponification Value = Molecular weight of KOH*(Volume of blank-Volume of Actual solution)*Normality of solution/Weight of sample taken to evaluate the Saponification Value, The Saponification value formula measures to determine the average molecular weight of fatty acids in a chemical compound or mixture, typically fats and oils. It's an important parameter in industries related to oils, fats, and soaps. Saponification Value is denoted by SV symbol.

How to evaluate Saponification value using this online evaluator? To use this online evaluator for Saponification value, enter Molecular weight of KOH (M_w), Volume of blank (V_b), Volume of Actual solution (V_a), Normality of solution (N) & Weight of sample taken (W_s) and hit the calculate button.

FAQs on Saponification value

What is the formula to find Saponification value?

The formula of Saponification value is expressed as Saponification Value = Molecular weight of KOH*(Volume of blank-Volume of Actual solution)*Normality of solution/Weight of sample taken. Here is an example- 187.0333 = 0.05611*(2E-05-1E-05)*0.5/0.0015.

How to calculate Saponification value?

With Molecular weight of KOH (M_w), Volume of blank (V_b), Volume of Actual solution (V_a), Normality of solution (N) & Weight of sample taken (W_s) we can find Saponification value using the formula - Saponification Value = Molecular weight of KOH*(Volume of blank-Volume of Actual solution)*Normality of solution/Weight of sample taken.
