If the redox reaction is energetically downhill, as in the Daniell cell above, (i.e. spontaneous, with ΔG < 0) then the reaction can be used to power electric devices. Cells that power devices are known asgalvanic cells. If the redox reaction is energetically uphill (i.e. non-spontane...

1、氧化还原反应(REDOX reaction)The basic definitionThe oxidation reduction reaction (REDOX reaction) is characterized by the corresponding changes in the chemical reaction of the elements before and after the reaction. The essence of the REDOX reaction is the gain or loss of the electron. The ...
It is a spectator ion in this reaction. 209 Figure 12.2 may be useful in deciding if an element has been oxidized or reduced. If an elements oxidation number increases (moves towards the right), then the element is oxidized. If an elements oxidation number decreases (moves towards the left...

F2+ 2 e−→ 2 F−(the reduction reaction) There is no net change in charge in aredox reactionso the excess electrons in the oxidation reaction must equal the number of electrons consumed by the reduction reaction. The ions combine to form hydrogen fluoride: ...
Electrochemical sensors are devices that convert the effect of the redox reaction on the surface of electrodes to electronically readable signals that show changes in potential, current, and conductivity. From: Polymeric Nanocomposite Materials for Sensor Applications, 2023 ...
Their results have shown that Fe2+ in the deep magma ocean would be disproportionate to Fe3+ and metallic Fe at high pressures (Figure 3), by the reaction 3Fe2+ = 2Fe3+ + Fe. The further modeling of Armstrong et al. (2019) has suggested that, at about 400 km depth, the ...
often below 5%. Triggered cargo release can occur through the action of GSH, which induces a thiol-disulfide exchange reaction, leading to the collapse or swelling of the nanocarrier. In the following section, we will briefly introduce the preparation methods for disulfide bond-driven nanocarriers ...
