FOR the past four years the writers have been engaged in the study of the crystallisation of sodium chloride from saturated natural brines under the influence of various factors, particularly the ...

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

As the attractions from the water molecules and their motion pulls the ions apart, the sodium chloride crystal dissolves. The positive areas of the water molecules surround the negative Chloride ions.
