    Please solution this problem One gram of zinc metal dissolved in a solution of hydrochloric acid with a concentration of 6 molars, dilute it to 250 ml. Take 25 ml of it into a polarography cell, and the polarogram shows a voltage wave at -0.65 volts (assigned to Cd impurities), a diffusion current equal to 32 milliamps. If we add to the cell containing the zinc solution 5 ml of Cadmium chloride concentration is 0.0005 molar, and when taking a second crystalogram, the diffusion current was 77.5 milliamps. Calculate the weight percentage of cadmium impurities in zinc metal.

    So the reference electrode is where oxidation occurs and attracts the chloride ions into the tube?

    I might be wrong, but shouldn't the Nernst equation reaction Quotient be Oxidation/reduction - for at least a galvanic cell?

    I agree with Ulyana's comment. I am electrical engineer and we are working on some potentiometric sensor and wanted to brush up my electrochemical knowledge. Awesome lectures however some lectures have same series number despite having different content. Can you please fix that by at least creating video list. Thanks for your hard work!!

    7:12 , BF3 has 2 C3 axis right? because turning it clockwise and anti clockwise makes different symmetry 'configuration'? Just want to confirm this.

    Hello everyone! I have a question about CV. It is known that current in CV depends on different controlling mechanisms: at low potentials before peak current there is surface control and after - diffusion control. Also it is known that changing of sweep speed give us information about surface or diffusion limitation of our reaction. But i cannot understand how type of limitation of our reaction connected with CV limitations at different potentials...
