Description / Table of Contents:
Aus konduktometrischen, elektrometrischen und kryoskopischen Messungen an den Systemen HgJ2—KCN—H2O und Hg(CN)2—KJ—H2O wird auf die Existenz folgender Komplexe in Lösung geschlossen: KHg(CN)2J (I), K2Hg(CN)2J2 (II), K2Hg(CN)4 (III).I und III ließen sich isolieren. Da I aus beiden Systemen in kristalliner Form zu erhalten ist, wird geschlossen, daß II weniger stabil ist und bei dem Kristallisationsprozeß in I übergeht. Die Messungen deuten ferner auf die Existenz eines Komplexes KHgJ2CN.
Notes:
Conductometric, electrometric and cryoscopic measurements of the systems: HgI2—KCN—H2O and Hg(CN)2—KI—H2O indicate the existence of the following complexes in solution: KHg(CN)2I, K2Hg(CN)2I2 and K2Hg(CN)4. Out of these, the first and the last complex have actually been isolated.The fact that from the systems: HgI2—2 KCN and Hg(CN)2—2 KI, the complex KHg(CN)2I gets crystallized, suggests that the complex K2Hg(CN)2I2 indicated by physicochemical measurements is unstable and gets converted into the more stable complex KHg(CN)2I during the process of crystallization. Some indication for the existence of the complex KHgI2CN has also been obtained. A modified method for the estimation of iodide in the presence of cyanide has been worked out.
