Question

Explain polarographic method to detrmine dissolved oxygen

Answer 1

Answer:

Pulsed Polarographic Dissolved Oxygen Sensors

A rapid-pulse DO sensor is similar to a steady-state polarographic DO sensor as both utilize a gold cathode and silver anode. Both steady-state and rapid-pulse sensors also measure dissolved oxygen by producing a constant voltage to polarize the electrodes 7

Answer 2

Answer:

We can measure dissolved oxygen through iodometry, colorimetry, electroanalytical methods, and luminescence. Iodometry, is a form of titration. Titration is where you use one substance that you know the concentration of (titrant) to determine the concentration of another substance (your sample).
