SCHEIDEN EN REAGEREN – H1
1.1- ZUIVERE STOF EN MENGSEL


ZUIVERE STOFFEN
 Stof is opgebouwd uit kleine deeltjes – moleculen (combinaties van 2 of meer atomen)
 1 soort molecuul of atoom – zuivere stof
 1 soort atoom – element
 Meerdere soorten atomen – verbinding


MENGSELS
 Meerdere soorten moleculen – mengsel
 Bij zuivere stof: smeltpunt/kookpunt (temp blijft gelijk tijdens overgang)
 Bij mengsel: smelttraject/kooktraject (temp loopt langzaam op tijdens overgang)




SOORTEN MENGSELS
 Oplossing – helder mengsel tot op de kleinste deeltjes gemengd (vloeistof met iets)
 Suspensie – troebel mengsel van vloeistof en vaste stof (vaste stof lost niet op) > bodem
 Emulsie – troebel mengsel van 2 vloeistoffen die snel weer ontmengen > tweelagensysteem




 Emulgator > niet ontmengen: hydrofobe staart (slecht mengen) & hydrofiele kop (goed mengen)
