2024年11月15日 · Soap and detergent, substances that, when dissolved in water, possess the ability to remove dirt from surfaces such as human skin, textiles, and other solids. The seemingly simple process of cleaning a soiled surface is, in fact, complex. Learn more about soap and detergent in this article.
Soap - Wikipedia
Soap is a salt of a fatty acid (sometimes other carboxylic acids) used for cleaning and lubricating products as well as other applications. [ 1 ] . In a domestic setting, soaps, specifically "toilet soaps", are surfactants usually used for washing, bathing, and other types of housekeeping.
How Does Soap Work? | Britannica - Encyclopedia Britannica
Soap molecules have on one end what’s known as a polar salt, which is hydrophilic, or attracted to water. The other end of the molecule is a nonpolar chain of fatty acids or hydrocarbons, which is hydrophobic—meaning that it’s repelled by water but …
Soaps And Detergents - Cleansing Action Of Soaps And Detergents …
The molecule of soap constitutes sodium or potassium salts of long-chain carboxylic acids. In the case of soaps, the carbon chain dissolves in oil and the ionic end dissolves in water. Thus, the soap molecules form structures called micelles .
Soap - Chemistry Encyclopedia - structure, reaction, water, uses, …
Soaps are cleaning agents that are usually made by reacting alkali (e.g., sodium hydroxide) with naturally occurring fat or fatty acids. The reaction produces sodium salts of these fatty acids, which improve the cleaning process by making water better able to lift away greasy stains from skin, hair, clothes, and just about anything else.
Soaps and Detergents - Chemistry LibreTexts
2023年1月23日 · The oldest amphiphilic cleaning agent known to humans is soap. Soap is manufactured by the base-catalyzed hydrolysis (saponification) of animal fat. Before sodium hydroxide was commercially available, a boiling solution of potassium carbonate leached from wood ashes was used.
Soap - Encyclopedia.com
2018年6月11日 · Soap is a salt of an alkali metal, such as sodium or potassium, with a mixture of “ fatty ” carboxylic acids. It is the result of a chemical reaction, called saponification, between triglycerides and a base such as sodium hydroxide.
[Class 10] Soaps and Detergents - Structure, Cleansing Action
2024年12月13日 · Soaps are made by heating animal fats or vegetable oils with concentrated sodium hydroxide solution (NaOH). Glycerol is formed as a side product. This process is known as saponification . A soap molecule consists of 2 ends: 1. Hydrophilic end. It is the ‘water loving’ part of the soap molecule.
How Soap Works - ThoughtCo
2019年7月19日 · Soaps are sodium or potassium fatty acids salts, produced from the hydrolysis of fats in a chemical reaction called saponification. Each soap molecule has a long hydrocarbon chain, sometimes called its 'tail', with a carboxylate 'head'. In water, the sodium or potassium ions float free, leaving a negatively-charged head.

2023年10月14日 · Soap molecules are amphiphilic, meaning they have both hydrophobic and hydrophilic regions. The hydrophobic tail, derived from the fatty acid component, avoids water and is attracted to oils and grease. On the other hand, the hydrophilic head is attracted to water.
