【摘要】 采用电动势法测定了由Ag/AgCl与Hg/Hg2Cl2所组成的多相反应体系热力学函数。对消法测定了以饱和KCl水溶液为电解质,以自制的Ag/AgCl/Cl-(a)(银/氯化银)电极与几个商品饱和Hg/Hg2Cl2/Cl-(a)(甘汞)电极组成的一系列原电池的电动势,在教学实践中发现,不同的商品饱和甘汞电极对测量结果存在很大差异。更多还原

【Abstract】 Thermodynamic functions of multiphase reaction system,which consisted of Ag/AgCl and Hg/ Hg2Cl2,were measured by EMF methods. In our teaching practice,the EMF testing results of electromotive forces of a series of galvanic cells,which consisted of KCl electrolyte saturated solution,self-manufactured Ag/ AgCl/Cl-(a)(silver/silver chloride) and commodity Hg/Hg2Cl2/Cl-(a)(calomel) electrodes,were found to be very different among the calomel electrodes.更多还原
