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 answer: B Hormones released in Solution 2 allowed it to maintain a higher pH. Sodium bicarbonate increases the temperature of a solution, which helped raise the pH of Solution 2. Sodium bicarbonate acted as a pH buffer in Solution 2. The water in Solution 1 had a lower starting pH than the water in Solution 2.
