Which food item has pH value between 2 and 3? This value makes it acidic.
Lemon juice (pH ~2.0 - 2.6)
Tomato juice (pH ~4.1 - 4.6)
Blackberry juice (pH ~3.2 - 4.5)
Apple juice (pH ~3.3 - 4.0)
Lemon juice (pH ~2.0 - 2.6)
Lemon juice contains high concentrations of citric acid, which results in a low pH typically between 2 and 3. This acidity is a direct measure of the concentration of hydronium ions in the solution.

Think of the pH scale as a 'sourness ladder'; the lower the number, the more intense the sour sensation on your taste buds due to the higher concentration of acid.
Low pH = Pungent/Powerful acidity (The lower the number, the stronger the acid).
pH=тИТlog10тАЛ[H+] тАФ Definition of pH
H3тАЛC6тАЛH5тАЛO7тАЛ тАФ Chemical formula for Citric Acid
The pH scale is defined as the negative logarithm of the hydrogen ion concentration, expressed as pH=тИТlog10тАЛ[H+]. Substances with a pH below 7 are acidic, where higher [H+] concentrations lead to lower pH values. Citric acid, a weak organic acid, dissociates partially in water to release these ions, significantly increasing the acidity.
The pH scale ranges from 0 to 14, where 7 is neutral.
Citric acid is the primary organic acid responsible for the sour taste in lemon juice.
Lemon juice acts as a natural preservative due to its low pH, which inhibits bacterial growth.
Used as a natural food preservative
Acts as an antioxidant due to Vitamin C content
High acidity can erode tooth enamel if consumed in excess
Can cause irritation to acid-sensitive digestive systems
Culinary flavoring and preservation
Cleaning agent due to its acidic nature reacting with mineral deposits
Lemon juice pH is generally 2.0 - 2.6.
Tomato juice has a pH of approximately 4.1 - 4.6.
Apple juice has a pH of approximately 3.3 - 4.0.
Blackberry juice has a pH of approximately 3.2 - 4.5.
A is correct тАФ Lemon juice typically has a pH between 2 and 3 due to its high citric acid content.
Always remember the pH range of common household items: Battery acid (0-1), Lemon juice (2-3), Vinegar (3), Milk (6.5), Blood (7.4), and Soap (9-10).
