Methodology:
The analytical method was used. (1) and (2) were placed in a vessel without contact to atmospheric moisture. With continuous stirring equilibrium was established in 6-7 hours. Salt content in saturated solutions determined by gravimetrically.
Sample Information:

- Source not specified; very pure reagent; dried in vacuum.
Measurement Errors:
Ambient temperature: ±0.1 K.
Mass concentration (m/v) (1): relative error ±0.1%.
System Components:
- Acetonitrile, $\ce{ C2H3N }$; [75-05-8] NIST WebBook
- Potassium iodide, $\ce{ KI }$; [7681-11-0] NIST WebBook
