Milk has a ph of 6. tomato juice has a ph of 4. therefore, tomato juice is: a. 20 times more acidic than milk. b. 100 times more acidic than milk. c. 100 times less acidic than milk. d. 20 times less acidic than milk

Option B

Explanation:

The pH scale is a way of determining a substance acidity, and it is logarithmic. As a result, each pH value is ten times more acidic than the next higher value. Therefore, pH 4 is ten times more acidic than pH 5 and 100 times (10*10) more acidic than pH 6.
