The protection from Tin Corrosion

In my project I will discuss two operation methods and make the impedance analysis to the tin rode within two case of study: * The thermal Analysis of the tin to be sure from its purity where we will work on it at high purity (99.9 %). * the impedance analysis of tin plate in sodium chloride with concentration 3 % first without any inhibitor as blank and after that we will add the inhibitor with differ concentration in a constant volume cell . Each time we will determine the impedance of the tin plate. * The impedance analysis of tin-plate in citric with concentration 0.3M and with sodium chloride NaCl 3% first without any inhibitor and secondary after adding the Arghel inhibitor with differ concentration. * The thermal analysis of the tin to determine the melting point the tin metal.
