In an experiment, acid was added to two solutions:
Solution 1: distilled water only
Solution 2: distilled water containing sodium bicarbonate
Then, the pH of each solution was taken.
Solution 1 had a final pH of 4.5, while Solution 2 had a final pH of 6.8.
Which of the following statements explains the difference between the two solutions?
Choose 1
(Choice A)
The water in Solution 1 had a lower starting pH than the water in Solution 2.
(Choice B)
Hormones released in Solution 2 allowed it to maintain a higher pH.
(Choice C)
Sodium bicarbonate acted as a pH buffer in Solution 2.
(Choice D)
Sodium bicarbonate increases the temperature of a solution, which helped raise the pH of Solution 2.
