SIFAT KOLIGATIF LARUTAN
By Anita Sari, S.Pd
2
konsentrasi (jumlah molekul) mempengaruhi sifat koligatif.
semakin banyak ion maka sifat koligatifnya semakin besar.
peta konsep
3
"semakin banyak zat terlarut yang dicampurkan dalam pelarut maka titik didihnya akan semakin besar"
Kenaikan Titik Didih
*air mendidih suhu 100 derajat celsius pada tekanan 1 atm.
4
"Semakin besar zat terlarut dalam pelarut maka titik bekunya akan semakin besar (suhu semakin negatif)"
Penurunan titik beku
*air membeku pada suhu 0 derajat celsius pada tekanan 1 atm
5
"Semakin banyak zat terlarut dalam pelarut maka tekanan uapnya semakin besar"
Penurunan Tekanan Uap Larutan
*air menguap pada suhu 20 derajat celsius.
6
Tekanan Osmotik
"peristiwa bergeraknya molekul pelarut ke arah larutan yg konsentrasinya lebih pekat melewati dinding semipermiabel"
Isotonis = dua larutan berbeda yg memiliki tekanan osmosis yg sama.
