    SULPHATE, CUPRIC MANQANOUS POTASSIUM contain 31-03 pts. of the salts at 11-14°, (v. Hiiuer.) 100 pts. sat. solution of CuSOj and MnSOj contain 37'09 pts. of the salts at 11-14°. (v. Hauer.) Very slowly sol. in sat. ZnSOj-f Aq, forming a double salt which separates. (Karsten.) 100 pts. sat. solution of CuSO^ and ZnS04 contain 32*70 pts. of tlie salts at 11-14°. (v. Hauer.) 100 pts. sat. solution of CUSO4 and FeS04 contain 17 43 pts. of the salts at 11-14°. (v. Hauer, J. pr. 103. 114.) More easily sol. in sat. K2S04-l-Aq than in Na^04 or MgSOj + Aq, forming a double sul})hate, which separates out. (Karsten.) K,>S04 and CuSOj mutually displace each other in saturated solutions. (Riidorff, Pogg. 148. 555.) When K2SO4 and CUSO4, both in excess, are dissolved in HoO, a maximum of solubility of 1561 pts. of the two salts in 100 pts. HoO at 25° is reached in 30 minutes, after which the solubility decreases. This result is obtained either by treating excess of the two salts with HoO at 25°, or cooling solutions of the two salts sat. at higher temp, to 25°. The salts are in the proportion of 5'2 pts. K0SO4 to 10 4 pts. CuSOj. If present in the same proportion as in their saturated solutions, 5 41 pts. K2SO4 to 10'13 pts. CuSOj would be required. If sat. solution of one salt is added to sat. solution of the other, IC2Cu(S04)2-f6H.,0 separates, as it is less sol. than either simi)lo salt, until a state of equilibrium is reached, after which there is no separation, contrary to Riidorff (see above). (Trevor, Z. phys. Ch. 7. 486.) Insol. in sat. (NH4).2S04-f Aq. (Engel, C. R. 102. 113.) Sol. in .sat. NaCl-f Aq. SI. sol. in sat. NH4C1-I-Aq, with separation of a double sulphate. _ Slowly sol. in sat. KNOj-t-Aq, with separa- tion of a double sulphate. Very slowly sol. in sat. NaNOg + Aq, with separation of a double sulphate. (Karsten, Berl. Abharidl. 1840. 10.) 100 pts. of a sat. solution in 40 % alcohol contains 0-25 pt. CUSO4-I-5H2O ; 20 % alcohol, 3-1 i.ts. ; 10 % alcohol, 13-3 pts. (Schiff, A. 118. 362.) Anhydrous CUSO4 is sol. in absolute methyl alcoiiol, but insol. in absolute ethyl alcohol. CuS04-fxH20 is insol. in methyl or ethyl alcohol. (Klcpl, J. pr. (2) 25. .'j26.) 100 pts. absolute methyl alcohol dissolve 1-05 i)ts. anhydrous CUSO4 at 18°. 100 pts. absolute methyl alcohol dissolve 15-6 i)tH. CuS04-f 5H,^0 at 18 ; 100 ])ts. 93-5 % methyl alcohol di.ssolve 0-93 pt. CuS04-f SI-LO at 18^ 100 pts. 50 % methyl alcohol dissolve 0-4 pt.;CuS04 + 5H20 at 18; 100 pts. ab.solute methyl alcohol dis.solve 13-4 iits. CuSO,+ 5H2O at 3°, 100 pts. absolute ethyl alcohol dissolve I'l pts. Cu.S04 + .'->H20 at 3°. (de Bruyn, Z. phys. Cli. 10. 786.) Sol. in glycetine (Pelouze), picoline (Unver- dorhen). Anhydrous CUSO4 is insol. in acetone. (Krug and M'Elroy, J. Anal. Ch. 6. 184.) Min. Chalcanthite. Cupric glucinum sulphate, CUSO4, 4GISO4-I- 2OII2O. Sol. in H2O. (Klatzo, J. B. 1868. 205.)
