Question
Transcribed Image Text:Use your diagram to find the equilibrium pH of the solution. Identify your solution point on the diagram.
![**Ammonia (NH₃) in Wastewater Treatment**
Ammonia (NH₃) is an important base, particularly in wastewaters. Understanding its behavior in aqueous solutions is crucial for effective wastewater management.
**Objective:**
Prepare a logC-pH diagram for a solution of 10⁻³ M of ammonia in water. Label each line with the name of the chemical species it represents.
**Chemical Equilibrium:**
\[ \text{NH}_4^+ \leftrightharpoons \text{NH}_3 + \text{H}^+ \]
**Equilibrium Constant:**
\[ K_A = 10^{-9.3} \]
**Instructions:**
1. Construct a logC-pH diagram for ammonia at a concentration of 10⁻³ M.
2. Identify and label each chemical species present, including NH₄⁺, NH₃, and H⁺.
3. Analyze the impact of pH on the equilibrium between NH₄⁺ and NH₃.
4. Use the given equilibrium constant to understand the balance between the species.
This diagram will help illustrate how changes in pH affect the concentration of various species in the ammonia equilibrium, which is vital for processes such as nitrification and denitrification in wastewater treatment.](https://content.bartleby.com/qna-images/question/2ebe91de-3090-46ac-907f-d0393c4d1db8/dae874c5-e0f2-45b8-99e0-3c41b04cbe39/oif3xl_processed.png)

- Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions.
