Answer:
The pH of the solution is expected to slightly increase to 4.49
Step-by-step explanation:
A buffer solution is 0.100 m in both hc7h5o2 and kc7h5o2 and has a ph of 4.19. What ph values would you expect from the addition of a small amount of a dilute solution of a strong base?
A.5.79 b.4.49 c.3.69 d. 3.89
The given pH of the buffer solution = 4.19
When a small amount of a dilute solution of a strong base is added to buffer solution, the buffer solution will become slightly more basic.
The pH will of the buffer will slightly increase to an extent. Therefore, the pH of the solution is expected to become 4.49.
So, option b. 4.49 is expected to be the correct choice.
