All the following statements are false about sodium chloride in the solid state except ____________
A. it exists as aggregate of ions B. it conducts electric circuit C. it exists as discrete molecules D. its ions are linked by metallic bonds
Correct Answer: A
Explanation
\(\Rightarrow\) Sodium chloride, being an ionic substance, is composed of ions rather than molecules \(\Rightarrow\) It can only conduct electricity when in aqueous or molten form. In the solid state, the ions are immobile and as such conduction is not possible \(\Rightarrow\) The ions are linked not by metallic bond but by electrostatic forces of attraction.
