titre ['taɪtə; 'tiːtə] 1.N the concentration of a solution as determined by titration 滴定率 2.N the minimum quantity of a solution required to complete a reaction in a titration 滴度 titration /taɪˈtreɪʃən/ 1.N an operation, used in volumetric analysis, in which a measured amount of one solution is added to a known quantity of another solution until the reaction between the two is complete. If the concentration of one solution is known, that of the other can be calculated 滴定法 目前一般实验室滴定分析采用的是人工滴定法,它是根据指示剂的颜色变化指示滴定终点,然后目测标准溶液消耗体积,计算分析结果。自动电位滴定法是通过电位的变化,由仪器自动判断终点。 volumetric analysis容量分析法
