Sodium chloride dissolving, animation

Videonummer 12081965
Sodium chloride dissolving. Animation showing the soluble chemical compound sodium chloride (NaCl, table salt) dissolving in water (H2O). This soluble salt is white in colour, with a spatula used to place some in a conical flask of water. The animation zooms in on the chemical at a molecular level. The atoms are shown colour-coded: chloride ions (Cl-, green) and sodium ions (Na+, purple). Water molecules are also shown (oxygen, red; hydrogen white). The water molecules are attracted to the ions, and disrupt the crystal lattice and pull the ions away and into solution. The water molecules are polar, with the hydrogen atoms (positive) attracted to the chloride ions (negative) and the oxygen atoms (negative) attracted to the sodium ions (positive). This animation also shows close-ups of the individual ions surrounded by water molecules, and the polarity of the water molecules and the resulting bonding.
