Question
Salts are usually hard and brittle. It takes lots of __________to pull them apart.
- Heat energy
- Water
- Pollution
- None of these
Hint:
Salts are ionic compounds therefore they require high energy to be broken.
The correct answer is: Heat energy
- Ionic compounds are brittle due to the strong bond between the positive and negative ions that make up the molecules.
- These positive and negative bonds create crystals in rigid, lattice structures. Applying pressure shifts the alignment of the ions and results in brittleness.
- It takes a lot of energy to break them apart from each other.
