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

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

Typical inorganic oxidizing agents are #"potassium permanganate,"# #KMnO_4#, and #"potassium dichromate,"# #K_2Cr_2O_7#.

The strongly coloured #KMnO_4# (deep crimson) is reduced to almost colourless #Mn^(2+)#:

#MnO_4^(-) + 8H^+ + 5e^(-) rarr Mn^(2+) + 4H_2O#

Orange dichromate is reduced to green #Cr^(3+)# ion:

#Cr_2O_7^(2-) + 14H^+ + 6e^(-)rarr 2Cr^(3+) + 7H_2O#

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