Study Notes
Protophilic Solvents
- Protophilic solvents are substances that have a strong affinity for protons (H+).
- Common examples include liquid ammonia, amines, and ketones.
- Protophilic solvents can enhance the acidic strength of weak acids, making them act like strong acids in solution.
- This phenomenon is known as the "levelling effect".
- The general reaction involving a protophilic solvent (S) and an acid (HB) can be represented as:
$HB + S \rightleftharpoons SH^{+} + B^{-}$
- In this reaction, the protophilic solvent (S) accepts a proton from the acid (HB), forming a solvated proton (SH+) and the conjugate base of the acid (B-).
- Weak acids are often used in the presence of strongly protophilic solvents to take advantage of the levelling effect.
