electrode potentials Flashcards
1
Q
cell potential
A
half cell potential compared to measured in comparison to a standard hydrogen electrode
under standard conditions
2
Q
electrode potential factors
A
temperature
pressure of gases
concentration of reagents
3
Q
standard measurements
A
made using high resistance voltmeters so no current flows and maximum PD is achieved
4
Q
more negative E standard
A
more likely to be oxidised
less likely to be reduced
5
Q
more positive e standard
A
more likely to be reduced
less likely to be oxidised
6
Q
standard hydrogen electrode
A
hydrogen gas in equilibrium with H+ ions of conc 1.00 moldm-3
hydrogen gas at pressure 100kPa
inert platinum electrode in contact with hydrogen gas and H+ ions
7
