Ion tétrathionate

WebIodine + thiosulfate ion → iodide ion + tetrathionate ion. Reaction 1 is relatively slow. As the iodine is formed, it is quickly used in reaction 2, which is relatively fast. The limiting reaction (Na2S2O3 solution) is a source of the thiosulfate ions. WebDéfinition. Un couple oxydant/réducteur est l’ensemble d'un oxydant et d'un réducteur qui sont conjugués dans les réactions d'oxydoréduction. Ils sont liés par une demi-équation d'oxydoréduction : l'ajout d'une quantité n d'électrons à un oxydant va donner un réducteur (son réducteur conjugué). On écrit : Ox + n.e - = Red ...
