हिन्दीThe concentration of hydrogen ion in a sample of soft drink is \( 3.8 \times 10^{-3}\text{ M} \). Given \( \log 3.8 = 0.58 \), what is the pH of the soft drink?
View Answer & Solution
Correct answer · Option A
2.42
Explanation
\( \text{pH} = -\log[\text{H}^+] = -\log(3.8 \times 10^{-3}) = 3 - \log(3.8) = 3 - 0.58 = 2.42 \).
