The solvent, which is suitable for a certain compound, may be totally unsatisfactory to other components in a sample.

Answer 2

Do a qualitative analysis to identify the approximate chemical composition of a sample

Question 3

Is an important source for standard reference materials

Answer 3

NIST or the National Institute of Standards and Technology
