electrode potentials

• what are the standard conditions for a cell

  gasses at a pressure of 100kPa

  temperature of 298K

  solutions at a concentration of 1 mol dm-3
• where do you draw the positive electrode in a cell diagram

  right hand side, except when using a standard hydrogen electrode as hydrogen is always on the left
• which electrode does oxidation occur at

  negative
• which electrode does reduction occur at

  positive
• which way do the electrons flow


  from the negative to the positive electrode
• standard electrode potential

  the E.M.F. of a half-cell compared with a standard hydrogen half-cell. measured at 298K, all solutions having a concentration of 1 mol dm-3 and all gasses at a pressure of 100kPa
• which way are reactions shown in the electrochemical series

  forward reaction is reduction
