针对酸性条件下用Mn^2+离子验证K2S2O8强氧化性的实验现象,讨论了在该反应发生时有可能发生的副反应.并通过对副反应在不同条件下的电动势的计算,从热力学的角度研究酸度、浓度和温度对副反应的影响,得到在酸性条件下用K2S2O8氧化Mn^2+离子产生单一实验现象的最佳条件.
This paper aims at experimental phenomena of K2S2O8 oxidated Mn^2+ in acid condition, discusses the possible side reaction when the reaction happens. And through calculates electromotive force of the side effects in different conditions, studies the effect of acidity, concentration and temperature for the side effects through viewpoint of thermodynamics, last, we get the best condition to produce a single experimental phenomena by K2S2O8 oxidated Mn^2+ in acidic condition.
