用 p H计测定溶液中某些离子的质量浓度 ,一般都是将 p H计与离子选择电极配合使用。如用氟离子选择电极与 p H计配合可测定溶液中 F- 的浓度。p H计一般用于测定溶液的 p H值和电位值。但经研究认为 ,与滴定装置配合 ,用数字显示p H计作为滴定终点显示仪 ,不用指示剂可测定溶?
Using p H meter to determine the mass concentration of some ions in the solution, the p H meter is generally used in conjunction with the ion-selective electrode. Such as fluoride ion selective electrode and p H meter with the determination of F-concentration in solution. The p H meter is generally used to determine the p H value and potential value of the solution. However, the study shows that, with the titration device with a digital display p H meter as a titration endpoint display, without indicator can be measured dissolved?
