Sodium Chloride Crystal

- The Larger green spheres represent the negative chloride ions.
- The smaller gray spheres represent the positive sodium ions.
Sodium Chloride Dissolving in Water




- The positive area of the water molecules surround the negative Chloride ions.
- The negative area of the water molecules surround the positive sodium ions.
- As the attractions from the water molecules and their motion pulls the ions apart, the sodium chloride crystal dissolves.
Sodium Chloride Dissolving in Water II

- The negative area of the water molecules surround the positive sodium ions.
- As the attractions from the water molecules and their motion pulls the ions apart, the sodium chloride crystal dissolves.
