	sample a	sample b
boiling point	low	high
conductivity in water	no	yes
solubility in water	no	yes

carl and sally designed an experiment to compare and contrast the properties of compounds. after designing their experiment, carl and sally tabulated the data in the table seen here. based on their data, compound b most likely represents what?

• a covalent compound
• an ionic compound
• a metallic compound

Explanation:

Ionic compounds typically have high boiling points, are soluble in water, and conduct electricity in aqueous solution (due to dissociated ions). Sample B has a high boiling point, is soluble in water, and conducts electricity in water—matching ionic compound properties. Covalent compounds often have low boiling points, don’t conduct electricity, and may be insoluble (like Sample A). Metallic compounds’ conductivity is more about solid-state, not just aqueous, so ionic is the best fit.

Answer:

B. an ionic compound
