摘要

合成了Mn(CH3SO3)2⋅2H2O、Co(CH3SO3)2⋅4H2O和Ni(CH3SO3)2⋅4H2O晶体水合物，并通过x射线衍射、电感耦合等离子体原子发射光谱和热重法对其进行了鉴定。用溶液量热法测定了298.15 K时在水中的溶解焓，并计算了锰、钴和甲基磺酸镍晶体水合物的标准生成焓。根据所得数据估计了在加性方案中，甲磺酸盐离子的焓对结晶甲磺酸盐形成焓的贡献。

Enthalpies of Formation of Crystal Hydrates Mn(CH3SO3)2⋅2H2O, Co(CH3SO3)2⋅4H2O, and Ni(CH3SO3)2⋅4H2O

Crystalline hydrates Mn(CH₃SO₃)₂⋅2H₂O, Co(CH₃SO₃)₂⋅4H₂O, and Ni(CH₃SO₃)₂⋅4H₂O are synthesized and identified via X-ray diffraction, inductively coupled plasma atomic emission spectroscopy, and thermogravimetry. Solution calorimetry is used to determine the enthalpies of dissolution in water at 298.15 K, and the standard enthalpies of formation of crystal hydrates of manganese, cobalt, and nickel methanesulfonates are calculated. The contribution from the enthalpy of the methanesulfonate ion to that of the formation of crystalline methanesulfonate in an additive scheme is estimated from the obtained data.
