The electrochemistry of corrosion and its prevention. Part I: basic electrochemistry
Donald Stewart B.Sc., M.Sc., F.I.Corr.Tech.
(Lecturer, Department of Environmental Engineering, University of Strathclyde The author has been teaching corrosion and its prevention since 1959 and during the past twenty years has come to the conclusion that there are still many people entering the corrosion prevention industry who have had no formal teaching in corrosion and operate, often remarkably well, purely on a rule of thumb basis. To help rectify this situation, the approach taken by Mr. Stewart in this series is based on his current lecture notes at the University of Strathclyde. He deliberately avoids the use of “as can be seen in Fig. 1”, but prefers to present explanatory diagrams adjacent to the text (which we are trying to follow in the layout of the articles) as in the manner they would be presented on the blackboard. Mr. Stewart was co‐author with Mr. D. S. Tulloch of the book “Corrosion and Prevention”, published by Macmillan in 1968. He has recently retired as Chairman of the Scottish Branch of the Institution of Corrosion Science and Technology. — Editor.)

Abstract
Introductory electrochemistry What appears to be a solid piece of metal is really a collection of individual metal atoms held together by mutual attraction. When it is placed in water, some of the more energetic atoms detach themselves and go into the water. When they do this they leave some of their electrons behind and emerge from the solid metal as positively charged particles called ions. This is usually shown as:
