Dissolve the sample as for zirconium. Add 2 ml hydrogen peroxide (30 %) and 2 ml hydrogen fluoride (50 %). Add the solution onto the column and elute as for zirconium, collecting the fraction of the eluate between 80 and 280 ml. Precipitate yttrium fluoride at 70-80 C and stir for one hour. Filter off on a membrane filter. Dissolve 50 mg vanadium(III) oxide, 50 mg manganese(II) chloride dihydrate and 50 mg cobalt(II) chloride hexahydrate in the filtrate and add dropwise 6 ml 0.5 M barium nitrate while stirring. Filter off the precipitate, wash with ethanol and dry at 80°C. 

Solution (a) The cation is a chromium ion and the anion is a chloride ion, Cl. The cation must be Cr3+ for electrical neutrality so chromium (a transition metal) is present as chromium(III). The 6HzO indicates that the compound is a hexahydrate so the compound is chromium(III) chloride hexahy-drate. (b) The cation is a barium ion, Ba2+ (the only cation that barium forms). The anion is a perchlorate ion, C104. Hence, the compound is barium perchlorate.

Calcium iodate hexahydrate can be prepared by a procedure similar to the barium iodate (Sec.8.6.2) using 2.5 g calcium chloride in 50 cm hot water to precipitate the calcium iodate. However, it is simpler to prepare it by double decomposition.
