Hi everyone, I was wondering where i could find information relating to depletion zone thickness for silicon p-n junctions. Am doing it for a project on solar cells. Also, what actually happens to the thickness of the depletion zone when the solar cells are active in closed or open circuit...

How does the listed salts acts as catalyst for the reaction and what property of the salts give rise to it being a better catalyst?

Using the definition of KD being ratio of concentrations in the 2 layers, try writing KD in terms of solute present in the 2 layers, A & B and the volumes V1 & V2 With the equation that you've made and A/(A+B) you should be able to slove this quite neatly

yeah the "real answer" you have looks rather strange. It has NO3- on both sides. Something looks wrong with this though "4e- +4H+ + 2NO3 - → NO3 - + NO + 2H2O " How did you arrive at 4 electrons?

part b talks about how the ion exchange resin could be 'recharged' with sodiums ions required in the process of softening water as mentioned in part a. Try this http://en.wikipedia.org/wiki/Ion_exchange_resin" page for a short and concise description of the process. The key word to...
