Review Questions

• Explain how the balanced chemical equation for the formation of sodium nitrate (NaNO3) is written.
  • The balanced chemical equation for the formation of sodium nitrate (NaNO3) is: Na + $\frac{1}{2}$O$_2$ + NO$_2$ → NaNO$_3$. This equation shows that sodium (Na) reacts with oxygen (O$_2$) and nitrogen dioxide (NO$_2$) to produce sodium nitrate (NaNO$_3$). The coefficients in the equation are balanced to ensure that the number of atoms of each element is the same on both sides of the reaction.
• Describe the role of sodium nitrate (NaNO3) in the preparation of halogens.
  • Sodium nitrate (NaNO$_3$) can be used in the preparation of halogens, such as chlorine gas, through its reaction with hydrochloric acid (HCl). The high solubility and oxidizing properties of sodium nitrate make it a useful compound in this process. When sodium nitrate reacts with hydrochloric acid, it produces chlorine gas (Cl$_2$), water (H$_2$O), and sodium chloride (NaCl). This reaction demonstrates the connection between sodium nitrate and the occurrence, preparation, and properties of halogens.
• Analyze the various industrial and agricultural applications of sodium nitrate (NaNO3) that are facilitated by its chemical properties.
  • Sodium nitrate (NaNO$_3$) has a wide range of applications due to its unique chemical properties. Its high solubility and oxidizing properties make it a valuable compound in various industries. In agriculture, sodium nitrate is commonly used as a fertilizer due to its ability to provide nitrogen, which is essential for plant growth. In the food industry, it is used as a preservative to prevent the growth of microorganisms. Additionally, sodium nitrate's oxidizing properties make it useful in the production of pyrotechnics and other explosives. The versatility of sodium nitrate is a testament to its importance in both chemical equations and the halogen group.
