Explain the cleansing action of soap. Why does soap not work in hard water

Why Does Soap Decrease Surface Tension?- Explain the cleansing action of soap. Why does soap not work in hard water ,Mar 27, 2020·Soap disrupts the cohesion of water molecules, allowing the water to soak into clothes in a laundry machine. Hard water, however, is somewhat resistant to the action of soap. The additional molecules that make the water hard tend to clump together with soap molecules and drag them out of the solution, leaving surface tension more intact.Cleansing Action of Soaps and Detergents - Carbon and its ...Soap and detergents: Soaps and detergents are the substances used for cleaning. Soap: A soap is the sodium or potassium salt of a long-chain fatty acids (carboxylic acid or glycerol) having cleansing action in water. A soap has a large non ionic hydrocarbon group and an ionic group.



Soap - Elmhurst University

Soap vs. oil vs. water: Water alone is not able to penetrate grease or oil because they are of opposite polarity. When grease or oil (non-polar hydrocarbons) are mixed with a soap- water solution, the soap molecules work as a "bridge" between polar water molecules and non-polar oil molecules.

How Soap Works

Jul 19, 2019·The organic part of natural soap is a negatively-charged, polar molecule. Its hydrophilic (water-loving) carboxylate group (-CO 2) interacts with water molecules via ion-dipole interactions and hydrogen bonding.The hydrophobic (water-fearing) part of a soap molecule, its long, nonpolar hydrocarbon chain, does not interact with water molecules.

Why soap do not form lather with hard water? - Brainly.in

Soap do not lather with hard water because the hard water contains too much of soluble salts of magnesium and calcium. So when the soap is trying to mix up/react with water to produce foam/lather they have to first react with the salts and then break them down so in this process most of the soap and time is wasted still proper lather is not produced.

The various micelles present in water do not come together to form a precipitate as each micelle repels the other because of the ion-ion repulsion. Thus, the dust particles remain trapped in micelles (which remain suspended) and are easily rinsed away with water. Hence, soap micelles remove dirt by dissolving it in water.
