Question

The lab question is “Based on a substance’s properties, how can you determine whether its bonds are ionic or covalent?” Fill in the box to answer this question with a hypothesis.

Hypothesis: If a substance contains ionic bonds, then its properties would include . . .

Answer 1

Hypothesis: If a substance contains ionic bonds, then its properties would include high melting and boiling points, the ability to conduct electricity when dissolved in water or melted, being soluble in water, and existing as a crystalline solid at room temperature. In contrast, if a substance contains covalent bonds, then its properties would include lower melting and boiling points, being poor conductors of electricity, and existing as gases, liquids, or low-melting-point solids at room temperature.
