This questions is relevant in part of the research paper that I am doing for 
Chemistry class. Throughout my research so far, I have found that when the 
electrodes are attached to the human body for an electrocardiogram, a salt 
solution is often applied to the probes, but I can't seem to find any 
information on why it is applied. PLease help!
