Identify the pH of lime juice.

Correct option is D

The correct answer is (D) 2.2

Explanation:
• Lime juice is highly acidic due to the presence of citric acid, giving it a pH of approximately 2.2.
• The pH scale ranges from 0 to 14, where values below 7 indicate acidity.

Information Booster:
• Gastric juice in our stomach has a pH of about 1.2, which helps in digesting food.
• Human blood has a slightly basic (alkaline) pH of around 7.4.

Additional Knowledge:
• 10 (Option A): Represents an alkaline substance like milk of magnesia.
• 1.2 (Option B): Matches the pH of gastric acid (hydrochloric acid in the stomach).
• 7.4 (Option C): The typical pH level of human blood.
