    Most of tlie metatungstates, however, are easily sol. in HoO. Tungstates iusol. in H2O are usually iusol. in dil. acids. Aluminum tungstate, Al2(W04)3 + SH^O. Precipitate. Insol. in H^O and Na2W04 + Aq. Sol. in (NH4)2Al2(S04)4 + Aq, NaOH + Aq, NH^OH + Aq. Easily sol. in H3PO4, H2C2O4, and H2C4H4O8 + Aq. (Lotz, A. 83. 65.) Sol. in 1500 pts. H2O at 15°. (Lefort, C. R. 87. 748.) AI2O3, 4WO3 + 9H2O. Sol. in 400 pts. HgO at 15°. (Lefort, C. R. 87. 748.) AI2O3, 5WO3 + 6H2O. Sol. in H2O, from which it is pptd. by alcohol. (Lefort.) Foi-mula according to Lefort is AI2O3, SWOg + 3H2O, 2WO3. Aluminum j?;aratungstate, 5AI2O3, 36WO3 + 46H20 = Al203, 7WO3+9H2O (■?). Easily sol. in an alum solution. (Lotz, A. 83. 65.) Ammonium tungstate, (NH4)2W04. Known only in solution. (NH4)4W30ii + 3H2O = 2(NH4)20, 3 WO3 + 3H2O. Sol. in HgO with decomj). Decomp. on air with evolution of NH3, and formation of ^amtungstate. Sol. in NH40H + Aq. (Marignac, A. ch. (3) 69. 23.) (NH4)4W50i7 + 5H2O = 2(NH4)20, 5WO3 + 5H2O. Soh at ordinary temp, in 26-29 pts. H2O with partial decomposition. (Marignac.) {■N'S,),WsO.^ + 8H2O = 3(NH4)20, 8 WO3 + 8H2O. Sol. in HjO. (Marignac.) Ammonium wic^fttungstate, (NH4)2W40i3. + 6H2O. (Marignac, A. ch. (4) 3. 74.) + 8H2O. Efflorescent. Very sol. in H2O. 1 pt. dissolves at 15° in 0-84 pt. H2O. (Lotz.) 1 pt. dissolves at ordinary temp, in 0'35 pt. H2O. (Riche.) Solubility increases rapidly with the tem- perature. Saturated solution at 40° is solid on cooling. SI. sol. in ordinary, insol. in absolute alco- hol. (Lotz.) Insol. in ether. (Riche.)

Ammonium ^jaratungstate, (NH4)ioWi204i = 5(NH4)20, 12WO3. (Marignac, A. ch. (3) 69. 25.) According to Lotz (A. 91. 49) and Scheibler (J. pr. 80. 208), formula is (NH4)6W7024 = 3(NH4)20, 7WO3. -f5HoO. (Scheibler, J. pr. 48. 232.) -HIH2O. Sol. in 25-28 pts. cold H2O. (Anthon.) ^„ ■, ^ „ ^ Sol. in 26-1 pts. H2O at 10-7°, and 5-8 pts. at 100°. (Lotz.) , „ . .
