Which buffer solution has maximum \( p H \) ?
(1) Mixture which contains \( 0.1 \mathrm{MCH}_{3} \mathrm{COOH} \) and \( 0.1 \mathrm{MCH} \mathrm{COONa}_{3}\left[\mathrm{pK}_{a}\left(\mathrm{CH}_{3} \mathrm{COOH}\right)=4.74\right] \)
(2) Mixture which contains \( 0.2 \mathrm{MCH}_{3} \mathrm{COOH} \) and \( 0.2 \mathrm{M} \) is \( \mathrm{CH}_{3} \mathrm{COONa} \)
(3) Mixture which contains \( 0.1 \mathrm{MNH}_{4} \mathrm{Cl} \) and \( 0.1 \mathrm{M} \) is \( \mathrm{NH}_{4} \mathrm{OH}\left[\mathrm{pK}_{b}\left(\mathrm{NH}_{4}^{+}\right)=9.26\right] \)
(4) All the solutions have equal \( p H \) which is 4.74
