  1. SOAPS AND DETERGENTS

  2. 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. INTRODUCTION

  3. WHAT IS A SOAP.? Soap is a sodium salt or Potassium salt of long chain fatty acids that has cleansing action in water.

  4. Some examples of soaps are : Sodium stearate Sodium Oleate Sodium Palmitate

  5. Sodium Stearate (has properties of soap) Reaction of soap with sodium hydroxide: Stearic acid Sodium Palmitate (has properties of soap)

  6. Well, How do you think soap is prepared.?? See how its prepared: https://www.youtube.com/watch?feature=player_detailpage&v=iIApHZDdHPY There’ssomething much easier than that..!! http://video.about.com/candleandsoap/Homemade-Soap-From-Scratch.htm GOT IT,FRIENDS..?? Now you can make soap at home itself..!!

  7. CHEMICAL REACTION: This is how its done in the lab..!!

  8. How does soap clean.. 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’

  9. See how the dirt is removed..!!

  10. WHAT ARE DETERGENTS? 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.

  11. DETERGENT, The king and DIRT, The Slave..!!

  12. Lets see how detergents are prepared.. Follow this link.. https://www.youtube.com/watch?feature=player_detailpage&v=6KVIMkOyoSM So easy to prepare detergent rite..!!

  13. SOAPS V/S DETERGENTS

  14. DISADVANTAGES OF DETERGENTS Detergents are not bio-degradable. They pollute water and soil.

  15. HOPE YOU ENJOYED LEARNINGTHE LESSON..!!
