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.

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.
When it comes to acid base calculations on the MCAT, weak bases are potentially the most confusing.
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.
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.
Ka and pH calculations for weak acids can be trick on the MCAT if you attempt a general chemistry approach.
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.
