电导分析法利用测量电导或电导的变化进行分析的电化学分析法。电导滴定法 测量滴定过程中电导G的变化,然后根据滴定曲线（有时以直线形式出现）求出滴定终点，从而算出欲测物质的量。电导滴定法可分中和滴定、沉淀滴定、络合滴定和氧化还原滴定。图1为滴定曲线，分三种类型。图1a是中和滴定的滴定曲线（见酸碱滴定法）,其中曲线1是强碱滴定弱酸的滴定曲线，滴定终点很明显，因为在反应中生成水，所以电导不断降低，直到终点时不再下降，过量的碱又使电导很快地上升；曲线2是弱碱滴定强酸，过了终点以后,由于弱碱的电离度很小，虽然加入过量的弱碱，电导几乎不变。图1b中的曲线 1是沉淀滴定的滴定曲线（见沉淀滴定法），例如在AgNO3+NaCl─→AgCl+NaNO3反应中，Na+代替Ag+，生成氯化银沉淀,所以滴定开始时电导变化不大，过了终点以后，继续加入氯化钠,电导上升；曲线2 是络合滴定的滴定曲线(见络合滴定法)，例如在酸性溶液中进行以下反应；Hg(NO3)2+2KCN─→Hg(CN)2+2KNO3，两个K+代替Hg2+,生成Hg(CN)2,滴定开始时,电导变化不大,过了终点以后,继续加入KCN，发生H++CN-+K+─→HCN+K+反应，由于HCN的电离度很小，因此电导下降。图1c是强碱滴定极弱的酸的滴定曲线，电导逐渐增大，过了终点以后，因加入强碱而使电导上升，终点在两直线的转折点。实际上，在终点附近的滴定曲线往往呈圆弧形或终点很不明显。这一现象与酸碱的强弱、沉淀的溶解度、络合物的稳定性和欲测物质的浓度有关,太稀的溶液(浓度在 10-3Μ以下)不容易得到准确的滴定结果。电导滴定法也可用于非水介质中。电导测量法 测量电导的电导池有不同的设计方案，一般由两个铂黑电极（面积为1厘米2）组成。测量电导实际上是测量电阻,图2是最常用的惠斯通电桥法的线路图。Rs是欲测的电阻(即欲测的电导)，R1大致等于Rs,C为可变电容。调节R2和R3，使电桥两端a和b的电位差等于零，由"指零"(G)来指示，它是一个耳机或交流检流计，当电桥平衡时：读出R1、R2和R3便可得出Rs。根据以上原理设计的各种电导仪可用于测定弱酸的离解常数、沉淀的溶度积以及检测水的纯度。实验室中高纯的电导水的电导率小于 0.1×10-6西（门子）/厘米，蒸馏水与空气中的二氧化碳达到平衡时平衡水的电导率约为 1×10-6西/厘米，一般电导滴定的溶液的电导率大于1×10-3西/厘米，所以水的电导率可以忽略不计。
