This green color results from an intense absorption at 610 nm. In the laboratory, K 2 MnO 4 can be synthesized by heating a solution of KMnO 4 in concentrated KOH solution followed by cooling to give green crystals: [3] 4 KMnO 4 + 4 KOH → 4 K 2 MnO 4 + O 2 + 2 H 2 O. This reaction illustrates the relatively rare role of hydroxide as a ...
