Apr 05, 2017 · 5-5. Silver Tree Redox Reaction. Description: A copper wire coil in a Christmas tree shape is allowed to sit in a solution of silver nitrate. Within an hour silver metal needles form on the wire. Concept: Copper metal is oxidized by the Ag1+ to Cu2+ and the Ag1+ ions are reduced by the copper metal to silver metal.

Redox Reactions - Examples, Types, Applications, Balancing
Corrosion, "rusting", is a redox reaction and a big problem in industry. A battery is a redox reaction. Redox is the transfer of electrons while acid/base chemistry involved the transfer of protons. Precipitation, unlike these two types of reactions, does not involve a transfer as such but the combination of existing ions in solution such that ...

We now understand that redox (oxidation reduction) reactions involve the transfer of electrons. Consider, for instance, the reaction between Copper ions (Cu+2(aq)) and Zinc metal (Zn(s)). The subscript (aq) on Cu+2 stands for “aqueous” and means that the ion is dissolved in water. The subscript (s) on Zn means that the Zinc metal is a solid.

Redox model. All the students explained oxidation and reduction as an electron transfer. Some of the students mixed up the meaning of oxidation and reduction, but they all indicated the use of the electron model in their explanations in all three situations. ... The overall chemical reasoning in this redox reaction seemed to be unproblematic ...
