21. It can act as either a strong oxidant or a strong reductant , and is quite corrosive to metals. 22. However, when you oxidize the copper in water, the most immediately available reductant is the water protons. 23. Activity greatly depends on the presence of a divalent copper ion and a reductant such as gallate or ascorbate. 24. In industry, hydrogen is the preferred reductant , whereas in the laboratory, tin and iron are often employed. 25. These are linked by plastoquinone, which does require energy to reduce cytochrome f for it is a sufficient reductant . 26. The desired compound is formed in the presence of nitrogen gas, dppe ligand, and magnesium turnings as the reductant : 27. Limited success has resulted from attempts to synthesize of a reductant molecule to TGF-? that displays a similar biological profile. 28. :Uhh, the whole point of the Lewis acid is to activate the oxidiser-- not the reductant / nucleophile. 29. Reductants causing reductive dissolution include natural electron donors such as ascorbic acid and { Fe ^ 2 + _ ( aq ) }.30. Most redox reactions happen better in either acid or base than pure water because pure water actually makes a lousy oxidant or reductant .
