Review Questions

• Explain how the ionic nature of NaBr relates to its properties and applications in the context of ionic and molecular compounds.
  • As an ionic compound, NaBr is composed of a positively charged sodium ion (Na+) and a negatively charged bromide ion (Br-). This ionic bonding results in NaBr having high melting and boiling points, as well as high solubility in water, which allows it to be used in various applications. The ionic nature of NaBr also contributes to its ability to dissociate in water, forming a solution of sodium and bromide ions that can be used in medical and industrial applications.
• Describe the role of bromine, the halogen element in NaBr, in the context of the occurrence, preparation, and properties of halogens.
  • Bromine, the element that forms the bromide ion in NaBr, is a member of the halogen group in the periodic table. Halogens are highly reactive nonmetals that occur naturally in the environment, often as compounds with other elements. Bromine, in particular, is a dense, reddish-brown liquid that is the third most reactive halogen. The preparation of NaBr often involves the reaction of bromine with sodium, and the properties of bromine, such as its high reactivity, contribute to the unique characteristics and applications of NaBr as an ionic compound.
• Analyze the significance of NaBr in the context of both ionic and molecular compounds, as well as the occurrence, preparation, and properties of halogens.
  • NaBr, as an ionic compound, is an important example of how the combination of a metal (sodium) and a nonmetal (bromine) can result in a stable, crystalline substance with distinct physical and chemical properties. The ionic nature of NaBr, with its high melting and boiling points and solubility in water, makes it useful in various applications. At the same time, the bromine component of NaBr links it to the broader properties and characteristics of halogens, such as their high reactivity and diverse uses. The occurrence, preparation, and unique properties of NaBr demonstrate the interconnectedness of ionic and molecular compounds with the fundamental behavior and applications of halogens in the field of chemistry.
