Question 2 • IL-Physical Science A-CR

The human stomach is an extremely acidic environment. This allows the stomach to break down food so nutrients can be absorbed as it moves through the digestive system. Stomach acid is more acidic than lemon juice, which has a pH of around 2.0.Which could possibly be the pH of gastric acid?

Answer
A
3.5
B
7
C
1.2
D
9.1

Explanation

On the pH scale, a lower number means a substance is more acidic. Lemon juice has a pH of about 2.0, so gastric acid must have a pH below 2.0. A pH of 1.2 fits; 3.5 is less acidic than lemon juice, while 7 is neutral and 9.1 is basic.
