Calculation of pH of NH4Cl Solution
Given:
- KB for NH4OH = 1.81 x 10^-5
- Concentration of NH4Cl = 0.01 M
Step 1: Write the dissociation reaction of NH4Cl
NH4Cl → NH4+ + Cl-
Step 2: Identify the ions present in the solution
NH4+ and Cl- ions are present in the solution.
Step 3: Determine the pH of the solution
- NH4Cl is a salt of weak base NH4OH and strong acid HCl.
- NH4+ ions react with water to form NH4OH and H3O+ ions.
- This reaction results in the production of hydroxide ions which increase the pH of the solution.
Step 4: Calculate the concentration of NH4OH
- Since NH4OH is a weak base, we need to consider the dissociation of NH4+ ions to NH4OH.
- Using the KB value, we can calculate the concentration of NH4OH.
Step 5: Calculate the pH of the solution
- Use the concentration of NH4OH to determine the concentration of hydroxide ions in the solution.
- Finally, calculate the pH using the concentration of hydroxide ions.
Conclusion:
- The pH of the 0.01 M NH4Cl solution at 25 degrees Celsius can be calculated using the concentration of NH4OH formed in the solution.
