EMF of a galvanic cell

Max voltage when negligibly small current flows

Standard hydrogen electrode ε° value

0.00 V (by definition)

Standard state concentration for solutes

1.000,extmolL−11.000 , ext{mol L}^{-1}

Standard state pressure for gases

100.0,extkPa100.0 , ext{kPa}

Symbol ε° represents

Standard electrode potential

Electrode potentials always refer to which reaction type?

Reduction reactions only

ε° of Cu2+\text{Cu}^{2+}/Cu half-cell

+0.34 V+0.34 \, \text{V}

ε° of Zn2+\text{Zn}^{2+}/Zn half-cell

−0.76 V-0.76 \, \text{V}

More positive ε° indicates

Stronger oxidising agent (readily gains electrons)

More negative ε° indicates

Stronger reducing agent (readily loses electrons)
