The surface of tin electrodes after potentiostatic polarization in 0.50 mole dm−3 sodium hydroxide solution has been examined by x‐ray photoelectron spectroscopy. Stannous oxide and hydroxide are shown to be present in the prepassive region. At higher potentials stannic oxide and hydroxide are formed. The thickness of the layer is evaluated over the potential range −0.95 to +0.40V using various models and is in the range 30–86Å.
