Electroplating Experiment
Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference as a measurable and quantitative phenomenon and identifiable chemical change with the potential difference as an outcome of a particular chemical change or vice versaThese reactions involve electrons moving via an electronically-conducting phase.
