Question

Four students are developing a model to illustrate covalent and ionic substances dissolving in

Answer 1

The students with ionic bonds have a better understanding of what the model needs to illustrate.

Explanation:

• When ionic compounds dissolve in water, they break apart into the ions that make them up through a process called dissociation.
• When placed in water, the ions are attracted to the water molecules, each of which carries a polar charge.
• If the force between the ions and the water molecules is strong enough to break the bonds between the ions, the compound dissolves.
• The ions dissociate and disperse in solution, each ringed by water molecules to prevent reattachment.
• The ionic solution turns into an electrolyte, meaning it can conduct electricity.
• While covalent compounds dissolve in water they break apart into molecules, but not individual atoms.
• Water is a polar solvent, but covalent compounds are usually nonpolar.
• This means covalent compounds typically don't dissolve in water, instead making a separate layer on the water's surface.
