What is the \(\mathrm{pH}\) of solution containing \(4.62 \times 10^{-4} \mathrm{M} \mathrm{H}^{+}\)ions?
- A 8.62
- B 4.64
- C 5.66
- D 3.34
Answer & Solution
Correct Answer
(D) 3.34
Step-by-step Solution
Detailed explanation
\(\begin{aligned} \mathrm{pH} & =-\log _{10}\left[\mathrm{H}^{+}\right] \\ & =-\log _{10}\left(4.62 \times 10^{-4}\right) \\ & =-\left[\log _{10} 4.62+\left(\log _{10} 10^{-4}\right)\right] \\ & =-[0.6646-4] \\ & =3.3354\end{aligned}\)
