Great lecture thank you for sharing it. I just have a question if you don't mind. I'm just getting confused between the potentiometry and Amperometry, what's the difference ? you used Daniel's cell @1:09 , I've seen few videos used it as galvanometric and others as Potentiometic cell , kindly can you shed some light on the differences between , the aftermentioned celles (i.e. Potentiometic/ Voltemetric cell , Amperometric , and galvanometric cells) your help will be much appreciated.
+mizouman Potentiometry is the measurement of electrical potential (i.e. voltage). Amperometry is the measurement of electrical current (i.e. amperage). An equivalent in terms of water falling over a dam is that potentiometry measures how high the dam is (how far the water falls), whereas amperometry measures how much water flows over the dam (volume, mass, moles, etc). Of course, an electrical cell will be measuring the movements of electrons instead of water molecules.
