Question

pure potassium hydrogen phthalate is used for the standardization of the sodium hydroxide solution. suppose that the potassium hydrogen phthalate is not completely dry. will the reported molar concentration of the sodium hydroxide solution be too high too low or unaffected because of the moistness of the potassium phthalate ? explain​

Answer 1

Answer:

the reported molar concentration of the sodium hydroxide solution will be too high.

Explanation:

The term "standardization" in science or in analytical Chemistry simply means the process involved in the determination of a standard or the concentration of a particular substance.

One of the advantages and the most important of the advantages of Standardization is that it Helps in making sure that we get a result with the least error.

So, let me explain the answer. The reported molar concentration of the sodium hydroxide solution will be TOO HIGH because the potassium hydrogen phthalate is NOT completely dry. The weight of the moisture will create an additional weight which will increase the weight of potassium hydrogen phthalate in the solution
