A student is given the task to determine if an unknown compound contains ionic or covalent bonds. Which of the following groups of tests would be best able to answer that question?
1) Determine the electrical conduction in the liquid state, mass needed for a 0.1 M aqueous solution, and color of the solid.
2) Determine the solubility in water, electrical conduction in the liquid state, and melting point.
3) Determine the density, solubility in ethanol (C2H5OH), and electrical conduction in the solid state.
4) Determine the solubility in water, electrical conduction in the solid state, and color of the solid.

1 Answer
2)
Explanation:
both ionic and covalent solids don't conduct elettricity, but ionic ones lead at liquid state and if their are solubilized in water. Not all of them, instead, solubilize in water as covalent or molecular solids. Some molecular solids (for example
