Solubility of an Ionic Compound (NaCl) Model

myminifactory

This model clearly demonstrates how ionic compounds like sodium chloride dissolve in water. The sodium ions, represented by orange particles, chlorine ions, shown as green particles, and water molecules are all scaled to size. The bulk crystal is shaped like a face-centered cubic structure. Individual ions can be printed separately and placed on top of the molecule in the same repeating pattern. By using the included water molecules, you can visually demonstrate how an ionic compound dissolves by removing the individual ions.\r\n\r\nFiles are available to print the model on dual extruder printers, which is highly recommended. For single extruder printers, the individual ions that are placed on top of the model can still be printed in separate colors.\r\n\r\nSome sodium ions located at the edge of the crystal may fall off when removing supports from the model.
