Answer:
Zn is negative...
Because Zn's reduction potential is negative value..which means lower -0.76v
Cu is positive...
Because Cu's reduction potential is Positive value..which means higher +0.34v
Ionic solution is solution containing ions...it transports different ions between two terminals..
Because modern world is based on power....We are using many electrical appliances which need Batteries. Batteries are essential components of most electrical devices
I think Zn is oxidized in to Zn^2+...So that appers as a burning...
