第31届中国化学奥林匹克竞赛第3题的理论与实验研究
Study on Question No.3 of the 31st Chinese Chemistry Olympiad
【摘要】 以第31届中国化学奥林匹克(决赛)试题第3题为素材,进行了理论及实验研究。理论计算表明,不同的观察标准可以导致不同的答案。而理论结果与实验结果并不统一,考虑活度系数的影响后2者取得高度的一致。
【Abstract】 This paper studied the third question of the 31 st Chinese Chemistry Olympiad,the calculation results showed that different critical values at which sediments could be observed may lead to different answers.It was found that the theoretical calculation was inconsistent with the experiment results.If the activity coefficient was taken into consideration,the theoretical results could be consistent with the experiment results.
