电动势法测定混合电解质CsBr+NaBr+H2O体系的活度系数OA北大核心CSCDCSTPCD
Electromotiye force measurements of activity coefficients for the ternary system (CsBr + NaBr + H2O)
采用电池Cs-ISE | CsBr(mA),NaBr (mB)| Br-ISE测定了298.15 K温度下CsBr+NaBr+H2O体系在离子强度I=0.01～1.00 mol/kg范围内,离子强度分数yB=0,0.25,0.50和0.75时的电动势,实验结果分别用Pitzer方程和Harned经验公式进行拟合,得到该体系的Pitzer二离子、三离子相互作用参数和Harned参数.拟合结果表明,Pitzer方程和Harned经验公式均能理想地适用于该三元盐水体系.
Activity coefficients of the ternary system (CsBr + NaBr + H2O) were determined by electromotive force (EMF) measurements using the cell: Cs-ion selective electrode(ISE) | CsBr (mA), NaBr (mB) | Br-ion selective electrode (ISE) at 298. 15 K, and over total ionic strengths from range 0. 01 to 1. 0 mol/kg for different ionic strength fractions (0. 25, 0. 5 and 0. 75). The experimental data were satisfactorily described via the Pitzer and Harned models. The Pit…查看全部>>
