Summary
This summary is machine-generated.

A new method for acid-base titrations accounts for carbonate impurities by performing neutralizations in a closed system. This approach successfully addresses the liquid-gas equilibrium of carbonic acid, even in extreme cases like neutralizing strong acids with sodium carbonate.

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):
