Electrochemical Definition and 60 Threads

According to some technical recommendation, we must be concerned about metal under ground structures (e.g. pipe lines) corrosion in neighbor of power transmission lines. Sinusoidal high current elements can produce eddy induced currents in their surroundings .The eddy currents in electrical...

I think this is a simple problem to solve, but I keep getting nonsense answers. The question: two reserviors held at constant osmolarity (say 1000 mOsm/l) are connected by a semipermeable membrane. A current of 1 uA is measured across the membrane. What is the volume of fluid that must flow...

Anyone knows how to derive Fick's law of diffusion: I=Jmf Given current density applied to electrochemical sensing: I= nAve where : I=current J=flux m=number of electrons F=faraday constant v=speed of particles n=number of charge carriers/vol A= cross-sectional area...

So my question is what is the difference between these cells? This always confuses me. I know that electrolytic cells are nonspontaneous and that their cathode is negative which means that electrons are going against their gradients here. I am also aware of the fact that a galvanic cells is...

The problem http://www.chem.iastate.edu/group/Greenbowe/sections/projectfolder/animations/CuZncell.html After veiwing the animation found at the website above answer these questions: Is there an electron transfer between species? Which species is losing electrons Which species...

i need help on writing redox reactions and with finding the electrode in oxidization and in reduction. oh and what are the three conditions under which the voltmeter reading will be 0 (zero)? THANKS:biggrin:

Hello everyone. I am having trouble with a question on electrochemical cells. I have to find the balanced REDOX reaction of the cell. All I am given is a diagram with the following information 1. Aluminum electrode submerged in 1 mol/L Aluminum Nitrate Al(NO3)3(aq) 2. Nickel electrode...

I have a problem that in my physics textbook, a source of EMF is just shown as a box having + and - terminals. The inner workings of that box need not be considered. They claim that although there is obviously an electrostatic force Fe due to this separation of charge, it is countered by a force...

Hello, everyone. I have a project for science fair that I would like to do, but I need verification to see if this will work like I think it will. My experiment's name is "The Effects of Electricity and Configuration on an Electrochemical Cell". It's wordy, but what can I do? Anyhow, my...

Hi all How to purify copper alloys electrochemically ? please describe all possible commerically feseable ways and also pls specify any commerical set ups /resource that can do the above process
