“…1, an unusual solubility domain for KIO 4 in aqueous KOH is observed. When the concentration of KOH is below 6 M, the solubility of KIO 4 rapidly increases with increasing KOH concentration to a maximum of 3 M KIO 4 . In alkaline solution rather than KIO 4 , potassium periodate exists as a soluble form of K 4 I 2 O 9 , 3 which may exist or I 2 O 9 4− , or perhaps in the partially protonated form such as H 2 I 2 O 9 2− , 19 and is consistent with a solubilization reaction increasing linearly with hydroxide, such as…”

“…4 The methodology consists of ͑A͒ preparing a solution of 50 mL 85% H 3 PO 4 and 50 mL 5 M H 2 SO 4 , which is diluted to 500 mL with deionized H 2 O; ͑B͒ a 0.25 g KIO 4 ͑or NaIO 4 ͒ sample is dissolved into solution A, and 6-8 drops of sodium diphenylamine sulfonate are added as an indicator. ͑C͒ The sample is then titrated with calibrated Fe͑NH 4 ͒ 2 ͑SO 4 ͒ 2 solution.…”

“…The techniques that were adopted involve the dissolution of the samples followed by direct colorimetric titration either using potassium dichromate or potassium iodate. [27] Other techniques, [28,29] which involve the dissolution of the samples in the presence of ammonium metavanadate (which will directly oxidize the liberated ferrous ions) prior to colorimetric titration, were also used. The initial results suggest that in all cases there were chemical interferences of some form due to the presence of a large concentration of nickel ions.…”
