The Availability Heuristic01:08

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Area of Science:

  • Analytical Chemistry
  • Physical Chemistry

Context:

  • Titration of weak bases is crucial in pharmaceutical analysis.
  • Phenol-water mixtures offer unique solvent properties for chemical analysis.

Purpose:

  • To describe potentiometric and conductimetric titration methods for weak bases.
  • To establish a classification of organic bases using spectrophotometry and a phenol-water solvent.
  • To characterize the phenol-water (90/10 w/w) solvent as a hemihydrate.

Summary:

  • Weak bases were successfully titrated using potentiometric and conductimetric methods in a 90/10 w/w phenol-water mixture.
  • Spectrophotometric analysis with 2,4-dinitrophenol allowed for a classification of organic bases, consistent with other solvent systems.
  • Dielectric constant measurements confirmed the phenol-water mixture functions as a hemihydrate, validating its use as a solvent.
