Theory Of Indicators (Noun)
Meaning
(chemistry) the theory that all indicators are either weak acids or weak bases in which the color of the ionized form is different from the color before dissociation.
Classification
Nouns denoting cognitive processes and contents.
Examples
- The theory of indicators explains how certain compounds change color in response to a change in pH.
- The pH-dependent equilibrium reactions of weak acids and bases form the basis of the theory of indicators.
- Within the theory of indicators, the key factor influencing the choice of an indicator for a particular system is the relationship between its ionization constant and the pH of the reaction.
- The acid dissociation constant and the pKa value play crucial roles in understanding the behavior of indicators according to the theory of indicators in chemistry.
- One major application of the theory of indicators in biochemistry is in studying enzymatic reactions that utilize acidic or basic substrates.
