Question

Volumetric analysis is preferred over gravimetric analysis when applicable because:
A.It requires less number of apparatus
B.It is more rapid
C.It is more accurate
D.All of the above

Answer 1

To answer this question, you should recall the concept of types of analysis. Gravimetric and volumetric analysis techniques are examples of analytical techniques which measure the amount of a certain constituent present in a given sample. The main point of difference between these two analytical techniques is the type of analysis i.e. in case of gravimetric analysis, the mass of the analyte is determined while on the other hand in volumetric analysis, the volume of the analyte is determined.

Complete step by step answer:
In comparison to other analytic techniques, volumetric analysis is quick, easy and approximate, good enough for most uses. A precision of $5\%$ is easy enough, even for a student $2\%$ can be done with care.
Gravimetric analysis is tedious and fundamental. It is used to standardize volumetric solutions. In laboratories, it has been proved that volumetric methods are generally more rapid, require less apparatus and are frequently capable of greater accuracy than gravimetric methods (due to easier calculations).
Hence, it qualifies for the features mentioned in the question.

Therefore, we can conclude that the correct answer to this question is option D.

Note:
Despite the more rapid results of volumetric techniques the gravimetric method analysis is more accurate than the volumetric method. The reason is that in the case of the gravimetric method the temperature of the solvent can be ignored, unlike volumetric method analysis. We know that the amount of solvent contained by a volumetric flask is dependent on the temperature while the weight of the solvent is not affected by temperature.
