Abstract:

The influence of temperature in the range 25 to 80°C on the dissolution of tin was investigated in an acidic solution at pH4 containing 0.1 to 1m NaCl. The corrosion current is slightly dependent on both the temperature and the Cl^– ion concentration. The main dissolution characteristics of tin are

$left( {frac{{partial E}}{{partial log i}}} right)_{{text{Cl}}^ - } approx frac{2}{3}frac{{RT}}{F}left( {frac{{partial log i}}{{partial log a_{{text{Cl}}^ - } }}} right) approx i$
