Saturated solution boils at 103-17° (Lowel), 103-5° (Mulder), 105° (Kremers), 100-5° (Grif- fiths), 100-8° (Gerlach). Crust forms at 102-9°; highest temp., 103-2 , and solution contains 43-9 pts.

Sol. with docomp. in HCl-l-Aq. More sol. in K2SO4, GUSO4, MgSO. + Aq than in H2O. (PfaH', A. 99. 226.) 100 pts. H2O dissolve 20-7 pts. CuSO. and 15-9 pts. Na2S04. (Rudorff, B. 6. 484.) Sol. in sat. MgS04, K2SO4, CuS04-fAq, but if more Na2S04 than can be dissolved is added to the GuS04-t-Aq, a large quantity of a double sulphate separates out. (Karsten.) See also under GUSO4, MgS04, and K2SO4. Slowly but abundantly sol. in sat. ZnS04 + Aq, with separation of a double salt after a few days. SoL in sat. NHjCl-t-Aq. Rapidly and abundantly sol. in sat. KCl-f Aq with pptn. of K2SO4. Na2S04-f IOH2O is sol. in sat. NaCl-t-Aq without pptn. If effloresced Na2S04 is used, a p2)t. of NaCl is caused at first, and subse- quently of Na2S04 + IOH2O. (Karsten.) Sol. in boiling sat. NaCl+Aq with pptn. of NaCl, but from cold solutions the Na2S04 separates out first. (Vauquelin.) Less sol. in NaCl-F Aq than in H2O. (Hunt, Am. J. Sci. (2) 25. 368.) Sol. in sat. KNOg-f Aq with pptn. after several hours. (Karsten.) Na2SO4-H0H2O is sol. in sat. NaNOg-t-Aq without pptn., but if effloresced Na2S04 is used, NaNOg is pptd. at first, and subsequently Na2S04-f7H20. Sol. in sat. NH4N03-J-Aq. (Margueritte, C. R. 38. 307.) Alcohol precipitates Na2SO4-f-10H2O from the cold saturated aqueous solution. (Brandes and Firnhaber.) Insol. in alcohol of from 0-817 to 0-90 sp. gr. (Kir- wan.) 1000 pts. alcohol of 0-872 sp. gr. dissolve 0-7 pt. Na^S04 at 12-5-15°; of 0-905 sp. gr. dissolve 3-8 pts. NaoS04 at 12-5-15°. Insol. in alcohol of 0-83-0-85 sp. gr. (Anthon.) From supersaturated solution in alcohol crystals with 7H2O are formed. (Schiff, A. 106. 11.) 100 pts. 10 % alcohol at 15° contain 14-35 pts. Na2S04-f lOHoO ; 20 % alcohol at 15° con- tain 5-6 pts. Na2S04-f IOH2O ; 40 % alcohol at 15° contain 1 -3 % Na2S04 + IOH2O. (Schiff, A. 118. 365.) Very si. sol. in abs. alcohol at ord. temi). ; somewhat more, though still exceedingly spar- ingly, sol. in abs. alcohol acidulated with H2SO4. (Fresenius.) Alcohol does not affect crystal HjO of Na2S04-f IOH2O. Sol. in glycerine. SI. sol. in cone. HC2H3O2. (Ure's Diet.) Not pptd. by addition of glacial HCjHgOo to Na2S04-fAq. (Persoz.) Min. Anhydrous, ThenardUc. -t-lOHgO, Mirabilite. Sodium hydrogen sulphate, NaHS04. Not deliquescent. Very sol. in HjO with decom])osition. Sol. in 2 pts. H2O at 0° (Link); 1 pt. HoO ■
