Surface area of the node during Electrolysis

  1. Oct 23, 2006 #1
    While doing electrolysis, Will the surface area of the node effect how much hydrogen is produced? Will it effect how well the current can pass through the water? Thank you

    It will not affect how much hydrogen is produced but it will affect the rate at which it is produced. Yes, generally larger electrodes will produce a larger current, however; if I remember correctly it is the current desnity that is more critical in electrolysis.
