Detergents and Soaps Flashcards | Quizlet- structures of soaps and detergents in water ,Soaps and Detergents have water-attracting (hydrophilic) groups on one end of the molecule and water-repelling (hydrophobic) groups on the other. Soap. Soap is a cleansing and emusifying agent made usually by action of alkali on fat or fatty acids and consisting essentially of sodium or potassium salts. Detergents.a What is a soap Name one soapb Describe the structureSOLUTION. (a) Soap is a mixture of sodium or potassium salts of various natural fatty acids and oils, which when used with water show cleansing properties. A soap contains a large, non-ionic hydrocarbon group and an ionic group COO−N a+. An example of a soap is sodium stearate (C17H35COO−N a+).



soap and detergent | Chemistry, Uses, Properties, & …

In order to perform as detergents (surface-active agents), soaps and detergents must have certain chemical structures: their molecules must contain a hydrophobic (water-insoluble) part, such as a fatty acid or a rather long chain carbon group, such as fatty alcohols or alkylbenzene. The molecule must also contain a hydrophilic (water-soluble) group, such as ―COONa, or a sulfo group, such as ...

alkyl ionic detergents, the micelles formed by bile acid salts are kidney shaped due to their rigid structure. As for ionic detergents, their micellar size is influenced by the concentration of the counter ion. Due to the low pK a (5–6) of the unconjugated bile salt, and low solubility of bile acids, their utility is limited to the alkaline ...

Simple Science | Difference Between Soap and Detergent

While detergents are free-rinsing (meaning they don’t leave a residue), soap needs a clear water wash after application or it will leave a film. Hard water is the enemy of soap. In hard water conditions soaps form scum. Soap scum affects more than just cleanliness; it can deteriorate fabrics and eventually ruin clothing or other surfaces.

Presentation on soaps and detergents - SlideShare

Jan 16, 2014·Presentation on soaps and detergents 1. Also known as Soaps Also known as Synthetic detergents. 2. SOAPS A soap is the sodium salt (or potassium salt) of a long chain carboxylic acid (fatty acid) which has cleansing properties in water. It is a salt of a strong base (NaOH) and a weak acid (carboxylic acid), so a solution of soap in water is basic in nature.

Mar 04, 2019·Cleaning a soiled surface is a four-step process. In the first step, the surface to be cleaned is made wet with water. In the second step, soap or detergent is applied to the surface to be absorbed. Soaps and detergents are also called surface-active agents, or surfactants. Surface active molecules present in soaps and detergents dissolve in water.

Although soap is a good cleaning agent, its cleaning capacity is reduced when used in hard water. Hardness of water is due to the presence of sulphates, chlorides or bicarbonate salts of Ca2+ or Mg2+ ions. Soaps are sodium or potassium salts of long chain fatty acids. When soap is added to hard water, the Ca2+ and Mg2+ ions present in hard ...
