Question

Which properties would be helpful in determining the Identity of the liquids, and which would not be helpful? Explain your answer. Boiling point, density, conductivity.

A) Boiling point and density would be helpful; conductivity would not be helpful.

B) Density and conductivity would be helpful; boiling point would not be helpful.

C) Boiling point and conductivity would be helpful; density would not be helpful.

D) Boiling point, density, and conductivity would all be helpful.

Answer 1

Boiling point and density are helpful in determining the identity of liquids because they are unique to each substance and influenced by intermolecular forces and composition. Conductivity might be less helpful but can still be valuable, especially when the liquid has unique conductive properties.

Step-by-step explanation:

In determining the identity of liquids, several properties can be helpful. Boiling point and density are useful properties because they are unique to each substance and can be used to distinguish between different liquids. The boiling point can vary greatly for substances with similar molar masses, which is influenced by the type of intermolecular forces present. Density, the mass per unit volume, can also help differentiate substances as it varies with the composition and phase of the material. Conductivity, both thermal and electrical, may be less helpful in identifying a liquid unless the liquid has distinctive conductive properties, as conductivity is more often used to classify materials like metals. In general, however, conductivity can still provide valuable information about a liquid, especially if it significantly differs from other substances.
