Multiple Choice
Which of the following is not a correct association between a chemical property and its description?
A
Density - Mass per unit volume
B
Solubility - Ability to conduct electricity
C
Flammability - Ability to ignite and burn
D
Acidity - Ability to donate protons
Verified step by step guidance

Step 1: Begin by understanding the concept of chemical properties. Chemical properties are characteristics of a substance that become evident during a chemical reaction; they include reactivity, flammability, acidity, and solubility.
Step 2: Review the definition of each chemical property mentioned in the problem. Density is defined as mass per unit volume, which is a physical property rather than a chemical one. Solubility refers to the ability of a substance to dissolve in a solvent, not its ability to conduct electricity. Flammability is the ability of a substance to ignite and burn, and acidity is the ability to donate protons (H⁺ ions).
Step 3: Identify the incorrect association. Solubility is incorrectly associated with the ability to conduct electricity. Solubility is about dissolving, while conductivity is related to the movement of charged particles.
Step 4: Understand why the other associations are correct. Density is a physical property, but it is correctly defined as mass per unit volume. Flammability correctly describes the ability to ignite and burn, and acidity correctly describes the ability to donate protons.
Step 5: Conclude that the incorrect association is between solubility and the ability to conduct electricity, as solubility is not related to electrical conductivity.
