Reactivity 3.1 (HL) Flashcards
1
Q
Is the dissociation of water into its ions an endo or exo process?
A
Endothermic
2
Q
Dissociation of water
A
H2O -> H+ + OH-
3
Q
What happens to Kw when temperature increases?
A
Kw increases as equilibrium shifts to the product side.
4
Q
Ka for weak acids
A
Weak acids slightly dissociate to their ions.
5
Q
Ka for weak bases
A
Weak bases are slightly ionised by accepting a proton in aqueous solution
6
Q
pH + pOH =
A
14
7
Q
The weaker the acid…
A
the smaller the Ka and the higher the pKa
