Q. The estimate of pH in lemon juice is
✅ Correct Answer: (A)
Less then 7
Explanation:
Lemon juice contains citric acid, so it is acidic.
- Acids have a pH less than 7.
- Neutral substances have a pH of 7.
- Bases (alkalis) have a pH greater than 7.
The pH of lemon juice is typically around 2 to 3, which is less than 7.
Options:
- (A) Less than 7 ✅ Correct
- (B) Equal to 7 ❌ Neutral
- (C) Estimation is not Right ❌ Incorrect
- (D) More than 7 ❌ Basic
Correct Answer: (A) Less than 7 ✅
Quick Revision:
- pH < 7 → Acidic (Lemon juice, vinegar)
- pH = 7 → Neutral (Pure water)
- pH > 7 → Basic (Soap solution, baking soda)
