Hoofdstuk 8
_________________________________________________________________________

8.1
Basische oplossingen:
- pH groter dan 7
- geleiden elektrische stroom
- nemen H+ ion op in water
- kleurt indicatoren
- belangrijkste basen: NH3, OH-, O2-, CO3 2-, HCO3-

Zuren:
- geleiden stroom
- staan H+ ion af in water

8.2
pH = -log [H+]

[H+] = 10^-pH

pOH = -log [OH-]

[OH-] = 10^-pOH

pH + pOH = 14,00

! Het aantal significante cijfers in de OH- moet even groot zijn als het aantal decimalen
(cijfers achter komma) in de pOH

8.3
Sterke base: reageert in aflopende reactie met water
Zwakke base: reageert in evenwichtsreactie met water

Bij het berekenen van de pH van een zwakke base reken je met de evenwichtsconstante:




Baseconstante: evenwicht van basen in water (Kb) BINAS 49

8.4
Zuur-basereactie: een reactie waarbij een zuur (donor) een H+ ion afstaat aan een base
(acceptor)
