Representative methods: permanganometry, iodometry, cerimetry,bromatometry, chromatometry

Pros: wide range of applications (determination of

g pp (organics, inorganics, ions, etc.)

Cons: limited selectivity, limited stability of titrants, onlyrelatively high concentrations can be determined

Titrant: 0.01-0.1 M solution, typically needs to be standardized

Conditions: sample has to be buffered (usually to an acidic pH)

Indicators: reversible (e.g. ferroin, diphenilamine, variamin blue, etc.) and irreversible indicator dyes, special action indicators (e.g. starch for I2, permangate colour, etc.)
