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?
Apple juice has a higher concentration of hydroxide ions than tomato juice does.
Apple juice and tomato juice have the same concentration of hydroxide ions.
Apple juice has a higher concentration of hydrogen ions than tomato juice does.
Apple juice has a lower concentration of hydrogen ions than tomato juice does.
Apple juice has a lower concentration of hydrogen ions than tomato juice does.
Apple juice has a lower concentration of hydrogen ions than tomato juice does.
To contrast 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. Based on this information, we can determine which statement accurately contrasts the two juices by understanding the relationship between pH and the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution.
pH is a measure of the acidity or alkalinity of a solution and is calculated as the negative logarithm (base 10) of the concentration of hydrogen ions in a solution. The more hydrogen ions present, the lower the pH, indicating a more acidic solution.
On the other hand, hydroxide ions (OH-) play a role in determining the alkalinity of a solution. The more hydroxide ions present, the higher the pH, indicating a more basic or alkaline solution.
Comparing the given pH ranges of apple juice (3.35 - 4.0) and tomato juice (4.1 - 4.6), we can see that apple juice has a lower pH range than tomato juice. This means that apple juice is more acidic compared to tomato juice, indicating that apple juice has a higher concentration of hydrogen ions.
Therefore, the correct statement to contrast the two juices is:
"Apple juice has a higher concentration of hydrogen ions than tomato juice does."
