Soap molecules are composed of long nonpolar "tails" with polar, negatively charged "heads" that arrange in a micelle formation: nonpolar interior, with a polar exterior shell surrounded by polar water. The polar exterior of soap micelles is negatively charged, and these negative charges repel one micelle from another, preventing coagulation. Soap is more effective in freshwater because higher salt ion concentration in seawater disrupts the ability of water to interact with the polar shells of micelles (fewer micelles can form in seawater because of the high concentration of salt ions in solution).
Answer for Ott's Chem 102
Detergent is a substance based on petroleum products. Soap is a waxy solid made from sodium hydroxide mixed with fats. The principal difference between soaps and detergents are in their composition. Soaps, on the whole, are made of materials found in nature, and detergents are labeled synthetic (although some of their ingredients are natural). Posted by Denise M. from GoPlanetEarth.com Detergents are human-made while soaps are produced naturally.
synthetic detergent contain hydrophobic and hydrophilic substance.the head(hydrophilic) contain sodium zedite.it can react with the ion in hard water and will become more effective.they can contact together. example of hard water is sea water,it contain ion such as calcium and magnesium.these ions will react with sodium zedite and make synthetic detergent is more effective cleanser in hard water.
No. Freshwater does not have the same amount of dissolved materials as sea water. Sea water has a much greater amount of salt dissolved in it.
Sea water is a complex solution.
Sea water is the densest among river water, distilled water, tap water, and sea water. This is due to the higher concentration of salt and minerals in sea water, which increases its density compared to the others.
in the sea
sea + water who ever put this is an idiot cus clearly it doesnt make ocean it doesnt even mix
This isn't even a sentence
soap, yeast, coffee/tea, kool aid, sea monkeys.
Egypt doesnt have sufficient water supplies because there are no lakes, rivers, seas, or oceans except for the nile and the red sea.
It doesnt surround it its on the Eastern side...the Irish sea.
the use little wooden bukets filled with water from the sea
This boiling point must be experimentally determined; this depends on the salinity and soap concentration. But more than 100 0C at standard pressure.
Yes you can but only 2-3 times a week with a very gentle soap. Use natural sea salt and water everyday otherwise.

The sodium salt of a carboxylic(fatty) acid. In modern terms it is made by boiling sodium hydroxide(lye) and palmitic acid together. The result is sodium palmate (soap). The palmate anion acts as the fats dirt absorber. The sodium cation allows it to dissolve in water. Manufacturers will then put in 'cream's and perfume, to make it 'smooth' and smell nice. Ordinary soap does NOT lather in salt(sea) water, owing to the 'common ion' effect (sodium cation). So a soap that lathers in salt water is made with potassium hydroxide. and palmitic acid. Other organic acids and animal fats canbe used in soap making.
sea water doesnt freeze faster than fresh water, fresh water freezes faster than sea water as it has a lower freezing point than sea water has as sea water contains salt which makes the boiling/freezing points increase therefore making the sea water freeze at a lower temperature.
