Soaps make soluble in water fats an oils, forming specific micelles.
The preparation of soap is called as saponification. When an ester reacts with a sodium salt of a carboxylic acid in the presence of a lye, it forms soap. All the reactants and products are organic.
Saponification is the process of creating soap. It typically involves reacting a strong alkaline (such as sodium hydroxide, potassium hydroxide, etc.) with a fatty acid or oil. The strong base reacts with the fatty acid to create a salt with a long hydrocarbon chain left over from the fatty acid or oil. Here's the reaction (using lye as an example): (hydrocarbon chain)-COOH + NaOH --> (hydrocarbon chain)-COONa + H2O When the cation bonds with the fatty acid/oil, it creates a new substance that possess the hydrophilic properties of the lipid hydrocarbon chain as well as the hydrophilic properties of the alkali metal (the sodium atom). Therefore, it can mix with both hydrophobic AND hydrophilic substances. Thus, if you need to wash away something greasy (hydrophobic), the hydrophobic chain of the soap will mix with the greasy substance, and a polar substance (such as water) can mix with the hydrophilic end of the soap as well...allowing you to mix grease with soap with water...and wash it away.
Yes, this process involves mixing animal fat with a solution of water and wood ash, commonly known as lye. The reaction between the fat and lye creates soap through a chemical process called saponification, where the fats are converted into soap molecules. This traditional method has been used for centuries to produce soap before the availability of modern industrial methods.
The chemical equation for soap formation in the presence of NaCl involves the saponification reaction of a fat or oil (triglyceride) with a strong base (such as sodium hydroxide - NaOH) to form soap (a fatty acid salt) and glycerol. The equation can be generalized as: Fat + NaOH → Soap + Glycerol. The presence of NaCl (sodium chloride) does not typically participate in the reaction but may affect the process by influencing the solubility and separation of the soap product.
Soap chemistry involves the chemical reaction known as saponification. This involves the irreversible, base-catalysed hydrolysis of esters- a class of organic molecules with a COO functional group. The process evidently uses artificial chemicals now, but soap has been with us for centuries. The Tudors in particular used animal fat (the source of the ester) and urine (the source of the base) to make soap- though one must speculate how appetising to use the end result was!
The term "Saponification" is an indication of what this reaction originally was used for: making soap. By boiling animal fat or lard with either potassium hydroxide or sodium hydroxide, the reaction, hydrolysis, produced glycerol and soap.
Saponification takes place in places where fat is stored in the human body.
Refluxing is done in the saponification reaction to maintain a constant temperature and ensure that the reaction proceeds to completion. By heating the reaction mixture to boiling and condensing the vapors back into the reaction vessel, it helps to drive the reaction forward and speed up the formation of soap.
Insoluble soaps are not likely to exist, they won't work when not IN water. For more you can trust on this: his process is called saponification: fat + sodium hydroxide -> Sodium salts of fatty acid (Soap) + glycerol
The preparation of soap is called as saponification. When an ester reacts with a sodium salt of a carboxylic acid in the presence of a lye, it forms soap. All the reactants and products are organic.
Glycerin and soap are the bye-products of saponification. The saponification value of glycerine are values of the percentage of lye it takes to convert one unit of fat, oil or fatty acid into glycerin.
what happen when fatti acid react with the NaOH
Sodium hydroxide and fat react to form fatty acid salts (essentially soap), and glycerin.
The simplest answer is probably - "lye soap". In broader terms, the reaction of fats with bases (like NaOH) is called "saponification" and the product is soap. Saponification involves hydrolysis of triglycerides, which are esters of fatty acids, to form the salt (sodium salt if the base is NaOH) of a carboxylates. In addition to soap, such traditional saponification processes produces glycerol.
Heating fat in an aqueous solution of sodium hydroxide produces soap through a chemical reaction known as saponification. This process breaks down the fat molecules into fatty acid salts and glycerol, resulting in the formation of soap as the end product.

The saponification number is a measure of the amount of alkali needed to saponify a certain weight of fat or oil. It indicates the average molecular weight of the fatty acids present in a sample. A higher saponification number indicates a higher average molecular weight of the fats or oils.
