What Happens when Stuff Dissolves?

How does an ionic compound like salt (NaCl) dissolve in water?

• It breaks apart into individual atoms.

• It breaks apart into individual ions.

• It remains as a single large crystal.

• It forms new covalent bonds with water molecules.

When a covalent compound like sugar (C2H4O2) dissolves in water, what happens to its molecules?

• The molecules break apart into individual atoms.

• The molecules remain intact and disperse throughout the water.

• The molecules combine to form larger structures.

• The molecules react chemically with water to form a new substance.

What is the primary difference in how ionic and covalent compounds behave when they dissolve in water?

• Ionic compounds form molecules, while covalent compounds form ions.

• Ionic compounds break into individual ions, while covalent compounds break into individual molecules.

• Ionic compounds break into individual atoms, while covalent compounds break into individual molecules.

• Ionic compounds do not dissolve, while covalent compounds always dissolve.

If a substance dissolves in water and its components separate into individual charged particles, what type of compound is this substance?

• Covalent

• Ionic

• Metallic

• Organic
