Question

An analytical chemist is titrating of a solution of ammonia with a solution of . The of ammonia is . Calculate the pH of the base solution after the chemist has added of the solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of solution added. Round your answer to decimal places.

Answer 1

To calculate the pH of the base solution after adding volume x of the solution, use the concept of titration. Find the concentration of OH- ions, then use the equation pH = 14 - pOH.

Step-by-step explanation:

In order to calculate the pH of the base solution after the chemist has added x of the solution, we need to use the concept of titration. Titration is a process of determining the concentration of an unknown solution by adding a solution of known concentration until the reaction between the two is complete. To find the pH, we can use the equation pH = -log[H+]. In this case, since ammonia is a base, we need to find the concentration of OH- ions, which is equal to the concentration of the base solution added. We can then use the equation pOH = -log[OH-] to find the pOH value and calculate the pH using pH = 14 - pOH.
