What is the pH of lemon juice?

Correct option is B

The correct answer is (b) 2.2.
· Lemon juice is acidic, and it has a pH around 2.2 due to its high concentration of citric acid.
· The pH scale ranges from 0 to 14, where values below 7 are acidic, 7 is neutral, and values above 7 are basic (alkaline).
Information Booster:
· Citric acid is a weak organic acid commonly found in citrus fruits like lemons, limes, and oranges.
· The acidic nature of lemon juice gives it its sour taste and makes it useful for culinary and cleaning purposes.
· pH scale: Each unit change on the pH scale represents a tenfold change in acidity or alkalinity. For example, a substance with a pH of 2 is 10 times more acidic than one with a pH of 3.
· Other acidic foods: Vinegar (pH ~2.5), tomato juice (pH ~4.1), and coffee (pH ~5).
