The purpose of this study was to analyze conception types related to Galvani and electrolytic
cells. Sanger and Greenbowe\'s interview protocols for the cells were used with modifications
in this study. These questions were administered and follow-up interviews were conducted to
pre-service chemistry teachers. This study revealed that several pre-service teachers in the
sample were confused about identifying the anode and cathode, understanding the charge on
the anode and cathode, understanding the need for a standard half-cell, predicting the products
of electrolysis, and understanding current flow in Galvani and electrolytic cells. In the case of
the purpose of the salt bridge, it was shown that pre-service teachers only thought that the salt
bridge is for ion movement of two solutions involving electrodes, but they didn\'t have the
conception that the salt bridge has a roll of connecting a circuit. Most pre-teachers had
misconception in electrolysis of solution taking no account of water electrolysis. As the results
of this study, it was possible that pre-service teacher\'s conceptual difficulties and
misconceptions were caused by insufficient expert knowledge, insufficient explanations of the
textbooks, and teachers having misconceptions.
