DPPH is often a effectively-known radical in addition to a lure ("scavenger") for other radicals. Consequently, level reduction of a chemical response on addition of DPPH is utilised being an indicator in the radical mother nature of that reaction. As a result of a solid absorption band centered at about 520 nm, the DPPH radical incorporates a deep violet coloration in solution, and it gets colorless or pale yellow when neutralized.
English is now the only real Germanic language to productively use "challenging" ⟨c⟩ (outdoors the digraph ⟨ck⟩) as an alternative to ⟨k⟩ (Despite the fact that Dutch makes use of it in mortgage text of Latin origin, plus the pronunciation of these words and phrases follows the identical hard/smooth distinction as in English).[citation needed]
