Define dissociation. Use a diagram to explain why NaCl(s) will dissociate when placed in water.
How do I draw the diagram?
We can draw diagrams on this site. Solid NaCl dissolves in water because the polar water molecules are attracted to the Na^+ and Cl^- and that attractions is enough to break the Na-Cl bond. Google this and you will get some good diagrams and explanations to explain just what is happening.
oops! We CAN'T (not can) draw diagrams in this site.
Dissociation refers to the process by which a compound breaks apart into its constituent ions when it is dissolved in a solvent, such as water. In the case of NaCl(s) (solid sodium chloride) dissolved in water, it will dissociate into Na+ ions and Cl- ions.
To draw the diagram, you can follow these steps:
1. Begin by drawing a circle to represent a water molecule (H2O). Label it as "H2O."
2. Next, draw a second water molecule nearby, making sure to leave some space between them.
3. Draw an arrow to represent the dissociation of NaCl(s). Place the arrow between the two water molecules.
4. Label the arrow with the chemical equation: NaCl(s) → Na+ + Cl-.
5. Draw a third water molecule near the first, and connect it to the Na+ ion with a dashed line to represent the attraction between ions and water molecules.
6. Finally, draw a fourth water molecule near the second, and connect it to the Cl- ion with a dashed line.
Your diagram should now show the dissociation of NaCl(s) in water, with sodium ions (Na+) surrounded by water molecules and chloride ions (Cl-) also surrounded by water molecules. This arrangement illustrates how the water molecules solvate the ions and stabilize them in solution.
Keep in mind that this is a simplified diagram, and in reality, there would be many more water molecules surrounding the ions due to the phenomenon of solvation. The diagram is a helpful visual representation of the process of dissociation in water.
