oxidation is the loss of electrons reduction is the gain of electrons Balance the half equation for the formation of aluminium during electrolysis: Al 3+ + e-→ Al. The balanced half equation is: ...

THE activation of copper by repeated oxidation and reduction is ascribed by previous authors to an increase in surface area 1, and our experiments have confirmed this conclusion. In the activated ...

IN experimenting with ethyl chlorophyllide, for specimens of which we wish to thank Prof. A. Stoll, of Basle, we observed the following reactions which illustrate a hitherto unknown property of ...

In this reaction, carbon is oxidised because it gains oxygen. At the same time, copper oxide is reduced because oxygen is removed from it.

"By controlling the oxidation states, we were able to significantly ... The findings could help create high-efficiency CO₂ reduction systems for the conversion of CO₂ into sustainable fuels ...
