在中学物理课中电解质溶液导电不是重点,但近年来出现了一批这方面的测验题、竞赛题或模拟题,激发了对这一问题的热烈议论。现将这类命题略举一二。(1)在一个电解池中,单位体积内的正、负离子数都是n,每个离子带电荷量为q,正、负离子的平均定向运动的速度都是仏电解槽的横截面积为S,试求通过电解槽的电流 Conducting electrolyte solutions in secondary school physics is not a priority, but a number of quizzes, contests or mock questions in this area have emerged in recent years, inspiring heated discussions on this issue. Now some of these propositions one or two. (1) In an electrolytic cell, the unit volume of positive and negative ions are n, each ion charge is q, positive and negative ions are the average directional motion speed 仏 cross-sectional area of ​​the cell S , Try the current through the cell
