Intermolecular Forces: The Synthesis and Properties of Soaps and Detergents. Background: A soap is the sodium or potassium salt of a long chain fatty acid. The fatty acid usually contains 12 to 18 carbon atoms. Solid soaps usually consist of sodium salts of fatty acids whereas liquid soaps usually are potassium salts of fatty acids.
Properties of Soaps and Detergents. Though similar in function, soaps and detergents differ in chemistry and performance. Students will examine the similarities and differences in the properties of soap, hand dishwashing detergent, and machine dishwashing detergent…
The Science of Soap Making in a Lab: Making soap doesn't seem like something you'd do in a lab, but it's actually more scientific than you'd think. Saponification is the soap making process, which uses the basic solution lye and different types of fats. The science behind soap …
Though similar in function, soaps and detergents differ in chemistry and performance. In this Consumer Chemistry kit from Innovating Science, students uncover the Properties of Soaps and Detergents. Experiment with soap, hand dishwashing detergent, and machine dishwashing detergent.
Detergents: Detergents have almost the same properties as soaps but they are more effective in hard water. Detergents are generally ammonium or sulphonate salts of long chain carboxylic acids. The …
Mar 16, 2015·Detergents are all around us in the lab – and that’s a good thing! Thanks to their chemical structure, detergents can solubilize and interact with many types of molecules, making them vital to research. To show you why detergents are such a good thing for scientists, we’ll go through six examples in molecular biology where detergents …
Preparation and Properties of Soap Experiment #7 Objective: To prepare soap by alkaline hydrolysis (saponification) of natural fats and test some of the chemical properties and cleansing power of soap relative to detergent. Introduction Soaps …
XI-Detergents-A-Soap-2 The Chemistry of Soap and Detergent Function All soaps and detergents contain a surfactant1 as their active ingredient. This is an ionic species consisting of a long, linear, …

In conclusion, soap is a substance, water soluble sodium salts of fatty acids, that is used to remove dirt and grime from a surface. It's molecules have a long hydrocarbon chain that has a negatively charged head. It's non polar hydrocarbon chain doesn't interact with water molecules that form micelles. The soap …
Explanation Bright orange flame Contaminant: Sodium What Does This Mean? The contaminants in the waters caused a reaction with the calcium in soap to create soap scum. We created a method to remove the contaminants, however, our detergent 1 was our best soap/detergent. Detergents
