Investigation into the NaI-KI-H2O system by NMR method

NMR studies of the NaI-KI-H2O triple system show that at 25 deg and 50 deg C the N+ and K+ ions preserve their ''structurizing'' and ''destructurizing'' properties no matter whether NaI or KI salts are added to pure water or to a solution of any KI or NaI concentration respectively. At -5 deg C the Na+ ion behaves as a ''destructurizer'' if NaI is added to water or to KI solution whose concentration is below the limit of complete hydration (LCH). If the KI concentration in the solution exceeds LCH, the Na+ ion acts as a structurizer at -5 deg C as well
