This reaction has been employed as a means of assaying copper ( II ) samples, since the evolved I 2 can be analyzed by redox titration.
2.
The indicator electrode must be suitable for the particular type of titration ( i . e . a glass electrode for acid-base reactions and a platinum electrode for redox titrations ), and should reach equilibrium rapidly.
3.
Acid-base titrations and redox titrations are often performed in which common indicators are used to locate the end point e . g ., methyl orange, phenolphthalein for acid base titrations and starch solutions for iodometric type redox process.
