Week 8.5: Back to the Column

I started testing my "poor man's induced polarization box"
I prepared it by getting a small plastic container and covering the top with cardboard box and a layer of styrofoam. Then, four stainless steel rods were taped around the sides and at the tip, only leaving ~1.5cm exposed to the outer environment. Then, those steel rods were inserted, not touching the bottom of the box but deep enough to stay submerged when water/solution is introduced. Then those rods were connected to the voltage source and voltmeter to take IP measurements.

It seems that there is a common y-value (in both cases) at 1Hz which all the concentrations are minimizing towards to.

Also, it seems that there is a clear trend throughout as; higher the concentration, lower the absolute value of phaseshift.
