$Difluorine, dioxygen, permanganate ion, dichromate ion, sulfur...$ $"Difluorine, dioxygen, permanganate ion, dichromate ion, sulfur..."$

Explanation:

Both $difluorine, and dioxygen$ $"difluorine, and dioxygen"$ are potent oxidizing agents, and readily accept electrons to give $F^{-}$ $F^-$ and $O^{2 -}$ $O^(2-)$ ions.

Typical inorganic oxidizing agents are $potassium permanganate,$ $"potassium permanganate,"$ $K M n O_{4}$ $KMnO_4$ , and $potassium dichromate,$ $"potassium dichromate,"$ $K_{2} C r_{2} O_{7}$ $K_2Cr_2O_7$ .

The strongly coloured $K M n O_{4}$ $KMnO_4$ (deep crimson) is reduced to almost colourless $M n^{2 +}$ $Mn^(2+)$ :

$M n O_{4}^{-} + 8 H^{+} + 5 e^{-} \to M n^{2 +} + 4 H_{2} O$ $MnO_4^(-) + 8H^+ + 5e^(-) rarr Mn^(2+) + 4H_2O$

Orange dichromate is reduced to green $C r^{3 +}$ $Cr^(3+)$ ion:

$C r_{2} O_{7}^{2 -} + 14 H^{+} + 6 e^{-} \to 2 C r^{3 +} + 7 H_{2} O$ $Cr_2O_7^(2-) + 14H^+ + 6e^(-)rarr 2Cr^(3+) + 7H_2O$

Both colour changes allow vizualization of the stoichiometric endpoints in titrations.
