10/10/2022·Soaps consist of a ‘-COONa’ group attached to a fatty acid having a long alkyl chain while detergents consist of a ‘-SO3Na’ group attached to a long alkyl chain. Surfactants are surface-active molecules present in soaps and detergents which help loosen surface tension and dissipate the force holding the dirt molecules together. Sample Questions

If the pH of a soap solution is lowered by acidic contaminants, insoluble fatty acids precipitate and form a scum. A second problem is caused by the presence of calcium and magnesium salts in the water supply (hard water). These divalent cations cause aggregation of the micelles, which then deposit as a dirty scum.
The manufacturing of soaps and detergents is a chemical reaction. The use of them is a physical action, not a chemical reaction. Why? Because when they are used, the end result …
09/05/2021·If you add soap or detergent, chemical reactions occur that emulsify grease and lower surface tension so you can remove oily grime. Even more reactions occur in laundry detergent, which may contain enzymes to break apart proteins and whiteners to prevent clothes from looking dingy. 7. Acid-Base Reactions:
Cleansing Action of Soap and Detergent Aim : To compare and contrast the effectiveness of cleaning action of soap & detergent Apparatus : 250cm3 beakers, 100cm3 measuring cylinder, glass rod Material : Detergent & soap solution, soft water, hard water ( distilled water + MgSO4 ), pieces of cloth (2cm x 2cm) with oily stain 7 8. Procedures: 1.
10/08/2021·the main steps in soaps/detergent making include: (i) selection of raw materials; (ii) reaction of the oils/fat with the basic salt; (iii) separating the reaction products where necessary; (iv) drying of the reaction product; (v) homogenizing the dried soap together with other additives; (vi) extruding the mixture to the right form; (vi) cutting …

23/03/2022·Soap is a cleaning substance that combines fat, lye, and water. This chemical process, called saponification, transforms lye, water, and fat into soap and alcohol through a hydration...
IV. Testing for the emulsifying power of soap, detergent, and distilled water on mineral oil In this test, you will investigate the behavior (reaction) of each reagent (soap, detergent, and distilled water) with mineral oil. Devise a method to set-up the experiment and get approval from your TA before proceeding with the test.
If the pH of a soap solution is lowered by acidic contaminants, insoluble fatty acids precipitate and form a scum. A second problem is caused by the presence of calcium and magnesium salts in the water supply (hard water). These divalent cations cause aggregation of the micelles, which then deposit as a dirty scum.
Surface active molecules, such as those found in soaps and detergents, dissolve when exposed to water. This solution is used to reduce surface tension, which is the force that holds …
Dispersion/suspension of the oil and dirt particles in the soap foam, preventing these particles from being redeposited on the surface. The Interaction of Soaps with the Skin Surgeons need to scrub. Health-care providers and employees of food services must take a range of precautions against the dissemination of microorganisms.
04/06/2020·Basic Definitions. Soap: A compound made of natural fats, oils, or butters and a strong alkali such as sodium hydroxide (also called caustic soda), or potassium hydroxide (also called caustic potash). Potassium-based alkali soaps are more water soluble and make a softer soap (Example: liquid castile soaps). Sodium-based alkali soaps make a less water soluble …
Soaps and detergents are widely used in our society. Soaps are the product of the reaction between a fat and sodium hydroxide: fat + 3NaOH → glycerine + 3 soap Soap is produced industrially in four basic steps.
Reaction Experiment 4: Soaps and Detergents There is some evidence that soap-making was known to the Babylonians in 2800 BC and to the Phoenicians around 600 BC. Surprisingly enough, it seems that soap was first used for cleaning textile fibers such as wool and cotton in preparation for the dyeing process and not for personal hygiene. Wool
21/09/2021·Soaps react with magnesium and calcium ions from hard water to form calcium or magnesium salts of fatty acids which do not dissolve in water and form a white precipitate that is called scum. 2RCOO−Na+ + Mg2+ → (RCOO)2 Mg + 2Na+ Scum sticks to clothes and makes washing difficult Highly branched soaps are not easily degradable and cause pollution.
21/09/2021·Detergents reduce the surface tension of water and are called surfactants. Detergents are soluble in water like soaps. Detergents are even soluble in hard water and do not form scum so they overcome the major limitation of soap. This is because the ionic group present in detergents does not interact with the Mg or Ca ions present in hard water.
