Question

Sot polarographic elect oxygen sensors oxygen measurements to be correct. The diffusion of the oxygen molecules in the sensor bead creates an oyen poor roe hut simulates a reduced concentration of oxygen. The concentration at the membrane must always be the equal to the concentrabien in the remainder of the sample. This condition can be met by (A) periodically replacing the sensor membrane. (B) measuring the dissolved oxygen at a very precise temperature. (0) stirring the sample at the appropriate rate until a steady flow of oxygen is detected at the membrane interface. calibrating the sensor membrane st the beginning of every measurement.

Explanation / Answer

Answer is option C i.e., by stirring the sample at the appropriate rate until a steady flow of Oxygen is detected at the membrane interface
