Trigger for a Zn oxidation reaction in a battery Reference

  1. Apr 20, 2015 #1
    Who is the trigger of the oxidation reaction. Copper which attracts electrons from the Zinc or solution which makes Zinc losing electrons and become positively charged. I am struggling to understand what actually makes Zinc to enter the solution and leave 2 electrons behind. If there is no wire between positive and a negative electrode of a battery Zn wont be able to give away 2 electrons or ZN electrode will still be able to gain a negative charge due to reaction with the solution. Thank you guys

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    The reaction happens for chemical reasons as described in http://hyperphysics.phy-astr.gsu.edu/hbase/electric/battery.html and anywhere else you might look.

    There is a charge built up on the zinc electrode. It doesn't have to go anywhere to exist as a charge. The ultimate potential is limited by the chemical reaction.
