Jan 30, 2023 · Indicators are organic weak acids or bases with complicated structures. For simplicity, we represent a general indicator by the formula HIn, and its ionization in a solution by the equilibrium, HIn ⇌ H + + In −. and define the equilibrium constant as Kai, Kai = [H +][In −] [HIn] which can be rearranged to give.
