Question
Define and illustrate the following terms clearly and concisely: (a) standard solution; (b) titration; (c) primary standard; (d) secondary standard.
Step 1
It is used as a reference to determine the concentration of an unknown sample. For instance, if we have a standard solution of sodium chloride with a concentration of 1M, we can use this to determine the concentration of an unknown sample of sodium chloride Show more…

A standard solution has to be used in a titration. AThe standard has to be a solution standardized by a primary standard, but the primary standard itself cannot be used as standard in a titration. B.The standard can be an unknown, as long as the concentration doesn’t change. C. The standard has to be a primary standard in order to obtain a reliable result. D.The standard can be either a primary standard or a solution standardized by a primary standard. E. The standard doesn’t have to have anything to do with a primary standard.
