\(\mathrm{pH}\) value of which one of the following is not equal to one?
- A \(0.1 \mathrm{M} \mathrm{CH}_{3} \mathrm{COOH}\)
- B \(0.1 \mathrm{M} \mathrm{HNO}_{3}\)
- C \(0.05 \mathrm{M} \mathrm{H}_{2} \mathrm{SO}_{4}\)
- D \(50 \mathrm{~cm}^{3} 0.4 \mathrm{M} \mathrm{HCl}+50 \mathrm{~cm}^{3} 0.2 \mathrm{M} \mathrm{NaOH}\)
Answer & Solution
Correct Answer
(A) \(0.1 \mathrm{M} \mathrm{CH}_{3} \mathrm{COOH}\)
Step-by-step Solution
Detailed explanation
\(0.1 \mathrm{M} \mathrm{CH}_{3} \mathrm{COOH}\) is not completely dissociated. Therefore, \(\mathrm{pH}\) will not be one.
