Question
**Title: Identifying Major Species in Weak Acid or Weak Base Solutions** **Introduction:** In this exercise, you will analyze the preparations of two aqueous solutions. Your task is to identify and write the chemical formulas of the major species present at equilibrium. You can omit water in these considerations. **Instructions:** For each solution, categorize the species into acids, bases, and others. Use the provided guidelines: 1. **Acids:** Write formulas of species acting as acids. 2. **Bases:** Write formulas of species acting as bases. 3. **Other:** Identify species acting as neither acids nor bases. *Note: Remember that \( \text{NH}_3 \) (ammonia) is a weak base.* **Solutions:** 1. **Preparation 1:** - **Solution Description:** 0.07 mol of HCl is added to 1.0 L of a 0.4 M \( \text{NH}_3 \) solution. - **Major Species Present:** - **Acids:** - **Bases:** - **Other:** 2. **Preparation 2:** - **Solution Description:** 0.3 mol of HNO₃ is added to 1.0 L of a solution containing both 0.8 M \( \text{NH}_3 \) and \( \text{NH}_4\text{Cl} \). - **Major Species Present:** - **Acids:** - **Bases:** - **Other:** **Graphical Representation:** There is a diagram showing a mock-up of a chemical process, indicating the areas for acids, bases, and other species to be filled based on the solution data. **Conclusion:** This exercise helps in understanding the behavior of weak acids and bases in solution and how to identify major ionic and molecular species at equilibrium.
