Electrochemistry
from MCAT Basics (from MedSchoolCoach) Hosted by Health Admissions IQ
In this episode of MCAT Basics, we’ll cover Electrochemistry. We start with the role of salt bridges in electrochemical cells and cover the intricacies of cell notation. We’ll also discuss how ions maintain charge balance, the importance of reduction and oxidation potentials, and how these elements come together in galvanic and electrolytic cells. We’ll also take a closer look at concentration cells and the critical Nernst equation, which helps us understand cell potentials under non-standard conditions.
