11) Which bottled water is neutral? Which brand of bottled water is most acidic? Which brand of bottled water is least acidic? a) Aquafina (filtered municipal water): pH = 5.96 b) Arrowhead (spring water): pH = 6.83 c) Crystal Geyser (spring water): pH = 6.93 d) Dasani (purified tap water): pH = 7.2 e) Evian (spring water): pH = 7.53 f) Fiji (spring water): pH = 6.65 g) Smart Water (distilled with added minerals): pH = 6.97
The Correct Answer and Explanation is:
To answer this, let’s first understand the pH scale and how it relates to acidity and alkalinity:
- The pH scale ranges from 0 to 14.
- pH 7 is neutral, meaning the water is neither acidic nor alkaline.
- A pH below 7 indicates acidity, and the lower the pH, the more acidic the water.
- A pH above 7 indicates alkalinity, and the higher the pH, the more alkaline the water.
Now, let’s analyze the pH values for each bottled water brand:
- Neutral water: A pH of 7 is neutral.
- The water with a pH closest to 7 is Dasani, with a pH of 7.2.
- Therefore, Dasani is the closest to neutral.
- Most acidic water: The water with the lowest pH is the most acidic.
- The water with the lowest pH is Aquafina, with a pH of 5.96.
- Therefore, Aquafina is the most acidic.
- Least acidic water: The water with the highest pH is the least acidic (or the most alkaline).
- The water with the highest pH is Evian, with a pH of 7.53.
- Therefore, Evian is the least acidic.
Summary:
- Neutral water: Dasani (pH = 7.2)
- Most acidic: Aquafina (pH = 5.96)
- Least acidic: Evian (pH = 7.53)
In general, bottled waters that are slightly acidic (below pH 7) may taste a bit more tart or sour, while those closer to or above pH 7 tend to taste neutral or more refreshing.
