Interpretation : The hydrogen ion concentration of orange juice is to be compared with the hydrogen ion concentration of tomato juice.
Concept Introduction : The negative logarithm of the concentration of hydrogen ions is the pH of a solution. The formula to calculate pH is given as
Answer to Problem 2STP
Correct answer: Option (B)
Compared to the hydrogen ion concentration of orange juice, the hydrogen ion concentration of tomato juice is 10 times lower.
Explanation of Solution
Reason for correct option:
The pH of orange juice is
The pH of tomato juice is
The formula to calculate pH is given as
The hydrogen ion concentration is given by rearranging the above formula.
To calculate the hydrogen ion concentration of orange juice, substitute the values in the above formula:
To calculate the hydrogen ion concentration of tomato juice, substitute the values in the above formula:
The hydrogen ion concentration of tomato juice is 10 times lower than the orange juice.
So, the correct answer is option B.
Reasons for incorrect options:
Options (A), (C), (D): All these options are irrelevant. The calculation of hydrogen ion concentration does not give these options.
