Cisplatin Cisplatin, cw-diaminodichloroplatinum (30.2.5.1), is made by reducing potassium hexachloroplatinate by hydrazine to potassium tetrachloroplatinate, which reacts with ammonia to give cisplatin (30.2.5.1) [73-77].

To 0.5 g. of potassium hexachloroplatinate(IY) in a quartz or Kel-F bottle, about 5 ml. of Freon 113 (CC12F—CC1F2) is added to act as moderator. Excess bromine trifluoride (1-2 ml.) is then added dropwise in the shortest possible time (a quartz or Kel-F rod may be used to assist pouring) until solution of the chloroplatinate is complete (bromine trifluoride and Freon 113 are immiscible). It is the aim of this procedure to combine minimum reaction time with minimum local heating of the mixture. It is usually necessary to shake the bottle ( care should be taken to avoid spills) to aid the solution process. As... 

Potassium trichlorotrifluoroplatinate(IV) may be identified by its x-ray powder photograph and infrared and ultraviolet spectra.3 Possible impurities are potassium hexafluorosilicatef and hexafluoroplatinate(IV) which may be detected by their infrared spectra (see subsection on properties of potassium hexafluoroplatinate(IV) below]. Any unreacted potassium hexachloroplatinate(IV) may be detected by its very intense (e = 24,500) ultraviolet absorption at 38,200 cm.-1 in aqueous solution.3 The product cannot be purified by recrystallization from water, since it disproportionates in aqueous solution. A... 

To 1 g. of potassium hexachloroplatinate(IV) in the quartz or Kel-F bottle about 6 ml. of bromine is added to act as moderator. Excess bromine trifluoride (3-4 ml.) is then added dropwise, and the resulting red solution is boiled until the bromine is expelled (3-5 minutes), leaving a clear yellow solution. This is then frozen in liquid nitrogen and transferred to a vacuum line where excess bromine trifluoride is removed by pumping, initially at 20°C. and later for half an hour at 120°C. to remove the last traces of BrFs. The product remains as. a pale yellow powder (yield 0.8 g., 100 %). It may be recrystallized from water, but it is best to extract with warm water, filter, and precipitate the salt from solution by addition of acetone. Anal. Calcd. for K2PtF6 K, 20.1 Pt, 50.4 F, 29.5. Found K, 19.8 Pt, 50.0 F, 29.1. 

If 40K is counted as potassium hexachloroplatinate (K2PtCl6) rather than KC1, would you expect beta self-absorption to be greater or less per mg/cm2 of precipitate Explain.
