The anode
Zn(s)/Zn2+(aq)//Au+(aq)/Au(s)
The voltaic cell
This is the anode.
Two electrodes in electrolyte solutions
Zinc is the anode.
The electrode that is oxidized in a galvanic cell ~
The anode creates a galvanic cell in which magnesium or zinc will be corroded more quickly than the metal of, let's sa a tank.
The electrode with the highest oxidation potential
In a galvanic cell, the less reactive metal is the cathode, where oxidation takes place. In this case the cathode is zinc.
It depends on the specifics of the cell, but in most simple galvanic cells, the anode slowly dissolves into solution.
A galvanic cell is a spontaneous reaction so electron flow will occur as long as a salt bridge is present.

The electrolyte of a commercial galvanic cell normally extends from anode to cathode without interruption by a salt bridge. A salt bridge is normally a teaching tool to help show that: 1. Galvanic half-cells do not produce voltage 2. Conductors and insulators are not necessarily salt bridges. An electrolyte must extend from anode to cathode before the galvanic cell can produce voltage. 3. The chemical composition of the salt bridge can differ from the electrolytes in the half cells. 4. Ions travel through the salt bridge between the cell's anode and cathode. Salt bridges raise more questions than answers. For example: 1. Can the difference between an electrolyte and a conductor be defined? 2. How do ions quickly move through a solid or a long electrolyte? 3. When salt bridge composition differs from the galvanic cell electrolyte(s), must the salt bridge chemically react with the galvanic cell electrolyte(s)? 4. Why does galvanic cell voltage remain nearly constant while anode to cathode distance doubles.
