Question

Determination of a Molar Mass by Freezing Point Depression: This experiment used Stearic Acid Experiments done in many first-year chemistry courses. They often use cyclohexane as the solvent and compounds such as p-dichlorobenzene, biphenyl, and naphthalene as the unknown solutes. Describe the advantages of this experiment over those.

Please answer in words and not equations, what are the advantages over the others?

Answer 1

Solution:

The following advantages of stearic acid during molar mass determination.

>>The determination of molar mass by stearic acid is considered as the less expensive because stearic acid is inexpensive fatty acid.

>> Stearic acid is less toxic fatty acid, hence the volume of waste can be reduced to zero if we use stearic acid as starting materials for other laboratory experiments.

>> It is considered as green chemistry experiment due to less expensive and less hazardous nature of stearic acid.
