hai and hai ,dah paham apa yang prof eika terangkan ? okay then ! let us move to the next topic :P
this time prof LIESA will teach you all about the cleansing action of soap .
like everyone know , soap is use as a cleansing agent to remove the organic dirt .
WHY ? this is because when soap is added into water , the soap molecules will dissociate into sodium (or potassium) ions and soap ions ( soap anions ) .
SOAP ions consist of two part , that is :
HEAT that
*consists of the anion region
*consists of the anion region
*is ionic
*is also called as hydrophilic region
*dissolves in water
TAIL that
*consists of the hydrocarbon region ( hydrocarbon chain )
*its molecules has covalent characteristic
*its also call as the hydrophobic region
*dissolves in grease or oil ( dirt )
secara AM nyaa . soap ion structure can be represented by by the structure below :
paham dak ? senang kan nak engat :)
okay . dah tahu tentang tu . mari teruskan . .
selain itu , soap molecules can reduce the surface tension of water to allow it to wet a material's surface better
when shaken , the water molecules will attract the soap ions and cause the greaseto detach from the surface of materials.
the soap bubbles also help to float the grease emulsion in the water . then . . when rinsed the grease will be remove together with the water
understand ? haa . jangan buat muka blurr . sila tengok gambar dekat bawah ni untuk lebih paham >
