Question

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

Answer 1

Answer:

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.
