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 […]
Acidity and Basicity of Alcohols Organic Chemistry Video
Alcohols are amphiprotic making them both acids and bases. This video shows you how to rank acidity and basicity of alcohols using charge, electronegativity, resonance, and inductive effect with practice examples along the way. (Watch on YouTube: Acidity & Basicity. Click CC for Transcription.) Links & Resources Mentioned In This Video: Arrhenius, Bronsted-Lowry, and Lewis Acids […]
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 […]
