HEATS OF DILATION, HEAT CAPACITIES AND APPARENT MOLAL ENTHALPIES OF MgB4O7-MgSO4MgCl2-H2O SYSTEMS AT 298.15K
【摘要】 本文研究了含硼四元水盐体系ＭｇＢ４Ｏ７－ＭｇＯ４－ＭｇＣｌ２－Ｈ２Ｏ及次级体系ＭｇＢ４Ｏ７－ＭｇＳＯ４－Ｈ２Ｏ和ＭｇＢ４Ｏ７－ＭｇＣｌ２－Ｈ２Ｏ在２９８．１５Ｋ时不同离子强度下的稀释热和热容，并将Ｄｅｂｙｅ－Ｈｕｃｋｅｌ极限公式应用到多元电解质稀溶液中，获得从高离子强度到低离子强度Ｉ为１９－０．０００１范围内的相对表观摩尔焓．
【Abstract】 he heats of dilution and heat capacitics of MgB4O7-MgSO4-MgCl2-H2O quaternary system and MgB4O7-MgSO4-H2O and MgB4O7-MgCl2-H2O subsystems were measured in the tonic strength range from 19 to 0. 1 at 298. 15K. The data of the heat of dilution were extrapolated to infinite dilution by use of the Dcbye-Huckcl limiting law to obtain relative apparent molal enthalpies over the ionic strength I range from 19 to 0.0001.
