The active dissolution of tin in acidic chloride electrolyte solutions — a rotating disc study

  • B. N. Stirrup
  • N. A. Hampson


The anodic dissolution of tin in acidic chloride electrolyte has been investigated using the rotating disc technique. The dissolution reaction has a Tafel slope of 64 ±5 mV dec−1 after the effects of diffusion are eliminated. The order of reaction with respect to Cl ion has been found to be unity. The measured currents were also found to depend onCH+. The suggested mechanism involves quasi-reversible charge transfer.

A possible explanation is given for the observed current-time behaviour at low anodic current densities.
