Soaps And Detergents are used for washing. It dissolves dirt, but some dirt will not dissolve in water. Soaps and detergents help water to remove dirt.
Soap is a sodium salt or Potassium salt of long chain fatty acids that has cleansing action in water.
Sodium stearate Sodium Palmitate Sodium Oleate
Stearic acid Sodium Stearate (has properties of soap ) Sodium Palmitate (has properties of soap)
See how its prepared: https://www.youtube.com/watch?feature=player_detai lpage&v=iIApHZDdHPY There’s something much easier than that..!! Soap-From-Scratch.htm GOT IT,FRIENDS..?? Now you can make soap at home itself..!!
This is how its done in the lab..!! CHEMICAL REACTION:
Soap dissolves in water. A soap molecule has a long hydrocarbon End and a short ionic end containing COONa+.The non-ionic hydrocarbon end has the property to repel water. (hydrophobic tail). The ionic end has the property to attract water. This end attaches itself to water.(hydrophilic head). The hydrocarbon end attaches to the dirt or grease to form structures called ‘micelles’
See how the dirt is removed..!!
Detergents are sodium salts of long chain benzene sulphonic acid or sodium salts of long chain alkyl hydrogen sulphate. A detergent molecule consists of a large hydrocarbon group that is non-ionic and a sulphonate (SO3- Na+) or a sulphate (SO4- Na+) group that is ionic.
DETERGENT, The king and DIRT, The Slave..!!
