MCQ practice · SSC Chemistry Board questions · Chapter 9: Acid-Base Balance
Which one is more alkaline?
Think it through first, then pick an option.
- a Blood
- b Urine
- c Pancreatic juice
- d Rain water
Answer and explanation
Correct answer: c Pancreatic juice
In Table 9.01 pancreatic juice has pH 8.1, the highest, so it is the most alkaline.
Why the other options are wrong
- a Blood: Blood is pH 7.43-7.45, lower than pancreatic juice at 8.1.
- b Urine: Urine is pH 6, on the acidic side, so not the most alkaline.
- d Rain water: Rain water is slightly acidic, not alkaline.
