CHEM LAB QUESTION:

You used a volumetric flask twice in this experiment. Once to dilute the sodium thiosulfate and once to dilute the potassium iodate. One set of students made up the sodium thiosulfate solution carefully, but overfilled the flask when making the potassium iodate. Another set of students overfilled the flask when making the sodium thiosulfate solution, but were careful to make the potassium iodate solution correctly. Which set of the students made the more serious mistake? Why?

**sodium thiosulfate: hydrated compound so potassium iodate is used to calculate molarity for experiement

Explanation / Answer

Answer-

A set of students who overfilled the flask when making the potassium iodate solution made the serious mistake because potassium iodate is used to calculate the molarity for experiment .
