초록

25℃의 NaCl-KCl-Methanol-Water계에서 NaCl의 활동도 계수를 이온 선택 전극을 이용하여 혼합전해질의 농도 1mol/kg까지 실험적으로 구하고 그 결과를 제시하였다. 예상 최대 실험오차는 5%이고 문헌의 저농도 데이터와 공통 농도 범위에서 비교적 잘 일치하였다. 또한 김과 이[1]의 혼합 강전해질-혼합 용매계에 대한 열역할 모델의 계산 결과는 실험치와 2% 내에서 일치하였다.

Activity coefficient of NaCl-KCl-Methanol-Water System was measured at 25℃ up to the total electrolyte concentration of 1mol/kg using ion selective electrodes. The maximum error expected was 5% and the experimental results showed close agreements with published data at low concentrations. Also calculated results by Kim and Lee’s thermodynamic mode[1]agreed with the experimental data within 2% error.
