Dissolving an ionic compound in water increases electrical conductivity because A. The water molecules electrostatically interact with the ions in the crystal and let the ions move freely.
How does dissolving an ionic compound in water increase electrical conductivity?
- A. The water molecules electrostatically interact with the ions in the crystal and let the ions move freely. TRUE. The interaction of water with the ions is known as solvation. The positive pole of water interacts with anions whereas the negative pole of water interacts with cations.
- B. The water molecules apply heat to break the ionic bonds in the crystal and let the ions move freely. FALSE. Even though there can be heat absorption during the solution of the ionic compound, the heat is not used to break the ionic bonds.
- C. The water molecules chemically react with the ions in the crystal and let the ions move freely. FALSE. There is no chemical reaction since the only thing that changes is the state of aggregation.
- D. The water molecules remove heat to break the ionic bonds in the crystal and let the ions move freely. FALSE. Even though there can be heat release during the solution of the ionic compound, the heat is not used to break the ionic bonds.
