Samenvatting Scheikunde H1

• Mengsel = bestaat uit meerdere sto-en
• Zuivere stof = een stof
o Van een stof andere stof maken kan met chemische reactie
o Stofeigenschappen = eigenschappen van een stof (kleur, smaak etc.)
§ Smeltpunt/kookpunt ook stofeigenschappen
o Dichtheid = combinatie van massa en volume.
§ Dichtheid = massa / volume (eenheid: kg/m3,
g/mL)
• Gevaarpictogrammen (Zie afbeelding)
• Elke stof is anders in 3 fasen
o Vast (S) (Onder smeltpunt)
o Vloeibaar (L) (Tussen smeltpunt en
kookpunt)
o Gas (G) (Boven kookpunt)
• Als een stof van de ene fase naar een
andere fase gaat: faseverandering
o Schematisch: Water (l) à Water (g)
• In dagelijks leven gebruik je graden
celcius als temperatuureenheid.
o In wetenschap gebruik je kelvin
§ T (K) = T(C) + 273,15
§ T (C) = T(K) – 273,15
• Zuivere stof heeft smeltpunt en kookpunt.
o Tijdens faseveranderingen blijft temperatuur gelijk
o Mengsel dan loopt temperatuur tijdens smelten/koken op:
smelttraject, kooktraject.
