When table salt, sodium chloride, dissolves in water, it dissociates into its respective cations and anions, Na+ and Cl-. These free ions in a salt-water solution allow electricity to flow through water.
How long does it take salt to dissolve in water?
Results. Boiling water (70 degrees) – fully dissolved in the 2 minute period. Ice cold water (3 degrees) – the salt crystals shrunk to half the size but did not dissolve.
What happens when salt dissolve in water?
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
