Potentiometry Flashcards
1
Q
Effect of electrolyte on solubility
A
Incr [NaCl], incr solubility (shielded by counter ions)
2
Q
ionic strength
A
mew = 1/2sum(cz^2)
Monovalent salts: mew=c
Other salts: mew>c
3
Q
activity
A
a=gamma*c
Neutral: gamma=1
Ions:
log(gamma)= -0.51z^2sqrt(mew)
4
Q
Standard cell notation
A
anode ll cathode
5
Q
Galvanic cell
A
E is positive, spon
6
Q
Electrolytic cell
A
E is negative, non-spon
