- A 1,5
- B 3,3
- C 2,4
- D 4,2
Answer & Solution
Correct Answer
(D) 4,2
Step-by-step Solution
Detailed explanation
\(\mathrm{pH} 1-7\) (acidic) = Black coffee, lemon juice, Human Saliva, Tomato juice. pH 7- 14 (basic) \(=0.2 \mathrm{M} \mathrm{NaOH}\), Lime water \(\left(\mathrm{Ca}(\mathrm{OH})_2\right)\)
