While contrasting the pH values of two distinct foods, Beth discovered that apple juice falls within a pH range of 3.35 - 4.0, whereas tomato juice falls within a pH range of 4.1 - 4.6. Which statement accurately contrasts the two juices?(1 point)

Responses

Apple juice has a higher concentration of hydroxide ions (OH-) than tomato juice does.
Apple juice has a higher concentration of hydroxide ions (OH-) than tomato juice does.

Apple juice has a lower concentration of hydrogen ions (H+) than tomato juice does.
Apple juice has a lower concentration of hydrogen ions (H+) than tomato juice does.

Apple juice has a higher concentration of hydrogen ions (H+) than tomato juice does.
Apple juice has a higher concentration of hydrogen ions (H+) than tomato juice does.

Apple juice and tomato juice have the same concentration of hydroxide ions (OH-).

1 answer

To contrast the pH values of apple juice and tomato juice correctly, we need to understand how pH relates to hydrogen ion (H+) and hydroxide ion (OH-) concentrations.

  1. Apple juice pH range: 3.35 - 4.0
  2. Tomato juice pH range: 4.1 - 4.6

Lower pH values indicate higher hydrogen ion concentration. Therefore:

  • Apple juice, with a pH range of 3.35 - 4.0, has a higher concentration of hydrogen ions (H+) compared to tomato juice, which has a pH range of 4.1 - 4.6, indicating a lower concentration of hydrogen ions.

Given this analysis, the accurate statement regarding the contrast between the two juices would be:

Apple juice has a higher concentration of hydrogen ions (H+) than tomato juice does.
