How does sodium chloride (NaCl) dissolve in water? Sodium chloride (NaCl) dissolves when water molecules continuously attack the NaCl crystal, pulling away the individual sodium (Na +) and chloride (Cl -) ions. This nonstop attack continuous until the whole NaCl crystal disintegrates. To understand this process at the molecular level, we must apply the three steps we previously discussed.

PDF Lattice Enthalpy NEW - WordPress.com Enthalpy change of solution and Enthalpy change of Hydration When ionic compounds dissolve in water, there is usually a temperature change. Sometimes this is exothermic (e.g. dissolving calcium chloride) and sometimes endothermic (e.g. dissolving ammonium nitrate). The experiments are easy to carry out in a laboratory, and the usual equations ...

Solubility - Purdue University We can generally assume that salts dissociate into their ions when they dissolve in water. Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.

Water molecules and their interaction with salt | U.S ... 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, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
