हिन्दीA solution contains \( 0.1\text{ M}\text{ NaOH} \). What is the \( \text{pH} \) of this solution at \( 298\text{ K} \)?
Correct answer · Option 1
13.0
Explanation
\( [\text{OH}^-] = 0.1\text{ M} = 10^{-1}\text{ M} \implies \text{pOH} = 1 \). Hence, \( \text{pH} = 14 - \text{pOH} = 14 - 1 = 13.0 \).
