    Hydrogen peroxide production in water electrolysis

    I'm trying to understand my textbook's answer to the following problem: Q: Electrolysis can under certain circumstances result in the production of hydrogen peroxide. At which electrode will this occur, cathode or anode? A: During the formation of hydrogen peroxide from water, oxygen is...

    Dissociation degree of polyprotic acids

    I can quickly calculate the dissociation degree of a monoprotic acid with the formula below (derived from the Hendersson-Hasselbach equation). I don't see any reason why this would not work also for polyprotic acids but I would like to confirm that it does. I would appreciate it if someone could...

    Compass and the direction of a magnetic field

    Cheers for the clarification.

    Compass and the direction of a magnetic field

    You're both right, I should've used solenoid as the system producing the electric field. However, if I was able to put the compass inside the magnet, then its north end would point towards north end of the magnet. This appeared to be counterintuitive in the sense that normally these ends appear...

    Compass and the direction of a magnetic field

    According to my physics textbook, one can find out the direction of a magnetic field by a small magnet. The magnet will line itself with the magnetic field with the north pole of the compass pointing in the direction of the field. http://dl.dropbox.com/u/345710/magnet%26compass.jpg...

    Electric Field Magnitude b/w Capacitor Plates

    Thanks, you instantly turned counterintuitive to intuitive. It's a shame that neither of my high school physics series mentioned that the formulas are based on an infinite plane. I guess that's obvious to most readers but to some (sigh) it isn't.

    Electric Field Magnitude b/w Capacitor Plates

    Electric field magnitude between capacitor plates independent of distance? [SOLVED] The electric field of a point charge Q is defined as E=\frac{F}{q}=\frac{\frac{1}{4\pi \varepsilon _{0}}\frac{Qq}{r^{2}}}{q}=\frac{1}{4\pi \varepsilon _{0}}\frac{Q}{r^{2}} where q is the test charge. The...
