Hi Neeraj Thank you for your comment. A fast stirring speed may produce a stirring funnel (also called vortex). If the sensor is directly placed into this funnel, the electrode may not be in contact with the solution at all, which may lead to incorrect measuring results. Therefore, you should adjust the stirring speed to a speed where stirring is as fast as possible to ensure a homogeneous sample while at the same time not creating a vortex that also could introduce CO2 into the sample.

How vortex formation affects the results in potentiometric titration? Can you please explain
