<human>:  What are the chemical properties of sodium chloride?
<bot>: Sodium chloride (NaCl) is a salt made up of equal parts sodium and chlorine. It is an ionic compound with a crystal lattice structure, and its physical and chemical properties are largely defined by its ionic interactions. The chemical properties of sodium chloride include a high solubility in water, a high melting and boiling point, low reactivity to other compounds, and a high electrical conductivity when dissolved in aqueous solutions.
