15 Οκτ 2022 · The objective of this laboratory is to make lye soap via the saponification reaction. The ancient Roman tradition called for mixing rain water, potash and animal tallow (rendered form of beef or mutton fat).
In this experiment, you will make soap from a fat or an oil by heating it with sodium hydroxide. You will precipitate the soap by adding it to a concentrated salt solution, and then you will collect the solid soap using vacuum filtration.
13 Ιαν 2012 · In this experiment, you will make soap from a fat or an oil by heating it with sodium hydroxide. You will precipitate the soap by adding it to a concentrated salt solution, and then you will collect the solid soap using vacuum filtration. You will then test the soap you made for its pH and foaming ability.
The products of the reaction are glycerol and a crude soap. The chemical formula of the soap is CH3(CH2)14COONa+. Draw the line-angle structure. Circle the portion of the molecule that is water-soluble and box the portion of the molecule that is fat-soluble. Why is the circle portion water-soluble? Why is the box portion fat- soluble?
This document provides instructions for making soap in a classroom laboratory setting. It details that students can successfully make soap by altering the oils, bases, fillers, and their proportions.
The purpose of this experiment is to make soap and study its properties. The soap will be prepared via saponification of a fat and oil with a solution of sodium hydroxide.
Modern soap making follows the same chemical process but uses safer sodium hydroxide and produces soap more quickly. The document describes the process of making soap via saponification. Saponification is the reaction between fats/oils and an alkaline solution that produces soap and glycerol.
