Acids & Bases - ionisation VS dissociation?

(1/1)

dux99.95:
Is this correct?

Bases - dissociate in water
Acids - ionise in solution

Thanks (:

Sort of, by the Arrhenius definition of acids and bases. However, this is NOT the definition that we use in the HSC. In the HSC, we define Acids/Bases by the Bronsted-Lowry definition, which states that

Acids are proton (Hydrogen ion) donors
Bases are proton (Hydrogen ion) acceptors

Tino_BCP:
So what is the difference between ionisation and dissociation??

ionisation formation of ions so from covalent stuff e.g. HCl ionises into H+ and Cl-
Dissociation would be stuff like NaCl into it's constituent atoms Na+ and Cl- so it's for weak bonds e.g. ionic bonds

having not done HSC not sure how in detail you need to know this stuff so I hope this helps!! :)
