MHT CET · Chemistry · Ionic Equilibrium
The hydrogen ion concentration of a solution is \(3.98 \times 10^{-6}\) mole per liter. The \(\mathrm{pH}\) value of this solution will be
- A \(6.0\)
- B \(5.8\)
- C \(5.4\)
- D \(5.9\)
Answer & Solution
Correct Answer
(C) \(5.4\)
Step-by-step Solution
Detailed explanation
\(\mathrm{pH}=-\log \left[\mathrm{H}^{+}\right]\)
\(=-\log \left(3.98 \times 10^{-6}\right)\)
\(=-\log 3.98-\log 10^{-6}\)
\(=-0.59+6=5.41\)
\(=-\log \left(3.98 \times 10^{-6}\right)\)
\(=-\log 3.98-\log 10^{-6}\)
\(=-0.59+6=5.41\)
