Hey, does anyone know any high oxidation state transition metal compound that are water soluble? I HAVE done some research into them. I can't find
many, so I was hoping you guys might know some. Praxichys - 23-10-2015 at 10:36
Uhh... KMnO4 has Mn in +7. Does that count?DalisAndy - 23-10-2015 at 11:07
I'm doing work with Chevreul's Salt..... So noDraconicAcid - 23-10-2015 at 14:54
Lots of them. What kind are you specifically looking for?Upsilon - 23-10-2015 at 15:51
Do you need them to be a salt of said metal, or a salt containing that metal? Like MnO2 vs KMnO4. If you are searching for the former, then your
options will be fairly limited. One possibility is chromium trioxide (CrO3) - note that it is a hexavalent chromium compound and must be handled and
disposed of carefully.DalisAndy - 23-10-2015 at 16:10
Anything that is analogous to cuprous sulfate or ferric sulfate. Mn +5 and up would work I thinkAmos - 23-10-2015 at 19:07

This makes no sense whatsoever. How can something where the metal's oxidation state is over 5 be "analagous" to either of the other two when they have
completely different oxidation states, configurations, crystal structures, etc.?ave369 - 24-10-2015 at 04:06
Transition metals in high oxidation states, with few exceptions, do not form basic compounds and salts as bases. The only exception I can remember is
tantalum (V) sulfate, which is unstable, very hydrolyzable and mentioned in exactly one Romanian inorganic chemistry reference book. These metals do
form halides and chalcogenides, but these are covalent rather than ionic, and, too, either hydrolyzed irreversibly or insoluble. So they are not, in
fact, salts.
You can also research salts of oxocations: such ions can be formed by some highly oxidated metals. Vanadium (V), uranium (VI) and several actinides
other than uranium do form stable oxocation salts, and metals such as molybdenum and tungsten form unstable oxocations.
