Trigger for a Zn oxidation reaction in a battery Reference

Click For Summary
SUMMARY

The oxidation reaction in a battery involving Zinc (Zn) is triggered by the interaction between Zinc and the solution, which facilitates the loss of electrons. Copper plays a role by attracting electrons from Zinc, but the primary mechanism is the chemical reaction that allows Zinc to enter the solution while leaving behind two electrons. Without a conductive wire connecting the positive and negative electrodes, Zinc cannot effectively release its electrons, leading to a buildup of charge on the Zinc electrode. The potential of this reaction is inherently limited by the underlying chemical processes.

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 won't 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
 
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.
