pH pOH Wheel Acid Base Calculations in MCAT Acid Base Chemistry

When you learn conversions between pH, pOH, H+ and OH- concentrations, it’s easy to get overwhelmed by all the different pathways and inter-conversions. This video shows you my pH/pOH wheel allowing you to easily identify where you are, what you need to calculate, and the most efficient path to get there. (click to watch on […]

Ka and pH shortcut for Weak Acids in MCAT Chemistry

Ka and pH calculations for weak acids can be trick on the MCAT if you attempt a general chemistry approach. Ice tables and quadratic equations are not only a waste of time, but nearly impossible without a calculator. This video shows you my shortcut for skipping the ICE chart and skipping the quadratic equation for […]
