11. Also hydrogen is a good reductant , but is dangerous and difficult to store. 12. This reaction effects N-methylation using formaldehyde with formic acid as the reductant . 13. For example, the preparation of magnesium by this method employs potassium as the reductant : 14. This can be done by adding a plutonium reductant before the first metal extraction step. 15. It is classified as a strong reductant . 16. Reductants in chemistry are very diverse.17. Hydrazine is a convenient reductant because the by-products are typically nitrogen gas and water. 18. Sulfite is with high affinity reduced by sulfite reductase to sulfide with ferredoxin as a reductant . 19. Reductive dissolution does not necessarily occur at the site of reductant adsorption, particularly for conductive specimens. 20. Subsequently, APS is reduced to sulfite, catalyzed by APS reductase with likely glutathione as reductant .
