A Study on the Probable Existence of Potassium lndium Alum with Radioactive Nuclei. Part I

Distribution study with Ga⁶⁷ and Fess as guests and potassium chrome alum and potassium aluminium alum as hosts has revealed that the requisite guest ions are taken up by the host components through mixed crystal formation. The study has been extended from tracer level to finite concentration of the guest ions. Constancy of λ confirms the previous finding that alums are mixed crystals forming in all proportions. Verifi­cation of the heterogeneous distribution law in case of In¹¹⁴ as guest and potassium chrome alum as host has been shown both at tracer lava! and at finite concentration of indium. Constancy of the heterogeneous distribution factor (λ) provides a positive evidence that thus far unknown potassium indium alum does exist. The value of the partition λ (0.18) is an indication that the slam is highly soluble. Causes of failure in its isolation has been discussed. Radioactive indicator thus finds an application in predicting the existence of the interesting compound which is thus far unknown.
