Water is a fascinating molecule to study, especially in reference to acid base chemistry. Both amphoteric and amphiprotic (explained in video) it will undergo ionization to yield both an acid and a base. This video breaks it down and covers important related calculations required for the MCAT. (click to watch on YouTube. Read Video transcript […]
Weak Bases pH pOH ka and kb Calculations in MCAT Chemistry
When it comes to acid base calculations on the MCAT, weak bases are potentially the most confusing. Not only do you have to convert from pOH to pH, but you may also find yourself having to find the kb from a given ka to start the process. And worst of all, you learned all this […]
pH and pOH for Strong Bases in MCAT Chemistry
Acid base calculations get trickier when dealing with bases since most MCAT style questions will ask about pH instead of pOH. This means you have to be comfortable calculating both OH- and H+ concentrations to find pOH and pH values. This video breaks it down with a few examples. (click to watch on YouTube. Video […]
MCAT Acid Base Chemistry Conjugates and Reactions
Video 1 in the MCAT Acid Base series is the introduction to acid/base concepts for upcoming calculations. You’ll learn how to recognize the ‘tricky’ acids, bases, and their conjugates, as well as how to relate and differentiate between Arrhenius, Bronsted-Lowry and Lewis acids and bases. Resources mentioned IN the video are linked below the video […]
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 […]
pH Calculations for Strong Acids in MCAT Acid Base Chemistry
pH Calculations are important for the MCAT, which means you must understand how to find both pH and H+ concentrations when given strong acidic solutions. This video walks you through the strong acids to memorize, as well as my quick-math method for finding pH from a given strong acid concentration. (click to watch on YouTube. […]
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 […]
pH and Hydrolysis for Salts of Weak Acids and Bases in MCAT Chemistry
Video 8 is the final, and potentially most intriguing video in my MCAT Acid Base series. This video shows you how to identify salts that will result in an acidic, basic, or neutral solution. You’ll learn how to think about each ion to help you determine its effect on pH. (Click to watch on YouTube. […]
