Difference and Application of Two Representation Methods of Standard Solution Concentration

The standard solution is required when determining and calculating the contents of the substances in water.There are two representation methods for standard solution concentration: amount-of-substance concentration and titration degree.Their applications are different.In this paper,the difference between two methods and their applications in water quality analysis were studied.Advantages and disadvantages of two methods were discussed.Their applicable scope as well as use of rules was summarized.
