1. Which of the unbuffered solutions, 1,2 or 3, was the most subject to pH change? Explain why.
2. What concluding statement can you make, on the basis of your observations regarding the fluctuations in pH for buffered and unbuffered solutions when small amounts of acid and base are added?
Explanation / Answer
1. Solution 1. Beacause base or acid was added in neutral solution and it shows a significant change.
2. Buffered solution try to maintain its pH when small amount of acid or base is adeed while vice-versa in case of unbuffered solution, so unbuffered shows a significant change,
