H4: ZOUTEN EN
ZOUTOPLOSSINGEN
4.1 – VORMING VAN EEN ZOUT
 Metaal staat elektron af > positief, moleculaire stof neemt 1 op > negatief (octeregel)
 Die 2 ionen vormen samen neutraal zout


DE IONBINDING
 Tussen 2 ionen ontstaat sterke ionbinding (sterker dan vanderwaalsbinding of waterstofbrug) > ionrooster
gevormd met gerangschikte positieve/negatieve ionen


POSITIEVE EN NEGATIEVE IONEN
 Enkelvoudig ion (lading) > Binas 40A
 Als er meerdere ladingen voor een atoomsoort zijn > aangeven met (romeins cijfer voor lading)
 Naam ion moleculaire stof = naam + ide + ion
 Samengestelde ionen > Binas 66B


NAMEN EN FORMULES VAN ZOUTEN
 Systematische naam zout = Naam positief ion + negatief ion (s bij kamertemperatuur)
 Lading moet neutraal zijn > verhoudingsformule kloppend maken
 Lading hoef je niet op te schrijven bij kamertemperatuur
 Aantal zouten hebben ook nog aparte naam: Triviale naam > Binas 66A


4.2 – WATER ALS OPLOSMIDDEL VOOR ZOUTEN
 Watermolecuul = dipoolbinding
 > waterstofkant (+) sluit moleculair ion in, zuurstofkant (-) sluit metaalion in (zout valt uiteen) > ontstaan
ion-dipoolbindingen
door hydratatie
(omringen van ionen
door water)
 Sommige ion bindingen
te sterk om verbroken
te worden > Binas 45A
