\(20 \, \text{mL}\) of \(0.1 \, \text{M}\) \(\mathrm{NaOH}\) is added to \(50 \, \text{mL}\) of \(0.1 \, \text{M}\) acetic acid solution. The \(\mathrm{pH}\) of the resulting solution is __________ \( \times 10^{-2} \) \((\text{Nearest integer})\)
Given: \( \mathrm{p}K_a(\mathrm{CH_3COOH}) = 4.76 \)
\( \log 2 = 0.30 \)
\( \log 3 = 0.48 \)
