What is the chemical equation of soap?
Soaps are denoted by the general formula RCOO-Na+, where R is any long chain alkyl group consisting 12 to 18 carbon atoms. Some common examples of fatty acids that are used in soaps are stearic acid having chemical formula C17H35COOH, palmitic acid having chemical formula C15H31COOH.
What is chemical element of soap?
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.
What is the scientific name of soap?
So, the chemical formula of soap is R-COO-Na where [R=CnH2n+1] Explanation: Sodium or potassium soap is produced by hydrolysis of oil and fats with caustic soda or caustic potash. Produced sodium or potassium salt is known as soap and the reaction is saponification.
What is the chemical formula of soap and detergent?
C17H35COONa or sodium stearate is the chemical formula for soap, while the chemical formula of detergent is C18H29NaO3S. A synthetic detergent is any synthetic substance other than soap that is an effective cleanser and functions equally well as a surface-active agent in hard or soft water.
What is lye in soap?
Lye in the form of both sodium hydroxide and potassium hydroxide is used in making soap. “Hot process” soap making also uses lye as the main ingredient. Lye is added to water, cooled for a few minutes and then added to oils and butters.
How do you calculate soap recipe?
Calculating the Amount of Soap Needed to Fill a Soap Mold
- Calculate the volume of the mold in cubic inches.
- Multiply the volume of the mold by 0.4 to find the total amount of oils in the recipe.
- Enter that amount of oils into an online lye calculator to get the final recipe quantities.
Is soap a mixture or pure substance?
Soap is not a compound, it is a mixture of sodium and potassium salts of long chain fatty acids containing 12 to 18 carbon atoms.
What is the difference between soap and detergent chemically?
Soaps are made from natural ingredients, such as plant oils (coconut, vegetable, palm, pine) or acids derived from animal fat. Detergents, on the other hand, are synthetic, man-made derivatives.

What is the pH of lye?
When the pH of a substance is above 7, it is a basic substance. When the pH of a substance is below 7, it is an acid substance. The further the pH lies above or below 7, the more basic or acid a solution is….Acids and bases.
