Interestingly enough, I still have this url on the clipboardjosephcollins said:Hi ppl. I'm asked a question: Iron filings are added to a solution containing the ions Cu2+, Fe2+, Fe3+, H30+ and Zn2+. Deduce what reactions occur from the standard electrode potentials.
A redox reaction is a type of chemical reaction in which there is a transfer of electrons between two or more substances. One substance loses electrons, becoming oxidized, while the other substance gains electrons, becoming reduced.
Oxidation is a process in which a substance loses electrons. This can occur through the loss of hydrogen atoms, the gain of oxygen atoms, or the transfer of electrons to another substance.
Reduction is a process in which a substance gains electrons. This can occur through the gain of hydrogen atoms, the loss of oxygen atoms, or the transfer of electrons from another substance.
An oxidizing agent is a substance that causes oxidation in another substance by accepting electrons from it. It is itself reduced in the process.
A reducing agent is a substance that causes reduction in another substance by donating electrons to it. It is itself oxidized in the process.
