🧪 Quick Study Guide

  • 🔥 Acidic oxides are oxides that react with water to form an acid or react with a base to form a salt and water.
  • 📝 Most acidic oxides are formed by nonmetals.
  • ⚗️ General formula: $X_mO_n$, where X is a nonmetal.
  • 🌍 Common examples include: Carbon dioxide ($CO_2$), Sulfur dioxide ($SO_2$), and Nitrogen dioxide ($NO_2$).
  • IUPAC Naming Convention: Name the nonmetal first, followed by 'oxide'. Use prefixes (di-, tri-, etc.) to indicate the number of oxygen atoms. For example, $N_2O_5$ is dinitrogen pentoxide.
  • 💡 Acidic oxides contribute to acid rain.
