Answer:
The pH of the final solution is 7.15
Explanation:
50 mL of 2.0 M of and 25 mL of 2.0 M of
were mixed to make a solution
Final volume of the solution after dilution = 200 mL
Final concentration of
Final concentration of
We use Hasselbach- Henderson equation:
Substituting the values:
Therfore, the pH of the final solution is 7.15
