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

If the substance has high melting/boiling point, if it requires high temperature to dissociate into simpler particles, if it's structure is hard and if it conducts heat and electricity quite frequently, then it would be "Ionic compound" otherwise, it will be covalent compound. (compound with covalent bonds).

Substance with ionic bonds, would include... (mentioned in first sentence)

Hope this helps!

Answer 2

off of EDG chemistry

(re write in your own words)

Sample hypothesis : If a substance is solid at room temperature, has a crystalline structure, dissolves easily in water, and conducts electricity well, then it likely contains ionic bonds.

(include in your hypothesis )

high melting and boiling points and therefore solid at room temperature

A crystalline structure

Ability to dissolve easily in water

Ability to conduct electricity well
