Total volume = 3V, [X-] = (0.03V/3V) = 0.01 M , pKa = 5.4 , pH = 5.4 + log (0.01/0.08) = 5.4 - 0.903 = 4.5 .

[Y-] = 0.1 M , pKa = 4 , pH = pKa + log ([Y-]/[HY]) = 4 + log (0.1/0.2) = 4 + log 0.5 = 4 - 0.301 = 3.7 .

[NH₄+] = 0.05 M , pKb = 4.74 , pOH = 4.74 + log (0.05/0.05) = 4.74 , pH = 14 - 4.74 = 9.26 .

pH = pKa + log ([Aâ»]/[HA]) is the scientifically accurate answer to this question. Within the study of pH and Buffer, this concept is well-established through extensive research and is documented in standard scientific literature. The specific properties, mechanisms, or characteristics of pH = pKa + log ([Aâ»]/[HA]) directly address what is being asked. Among the other options, pH = log [Hâº], pH = -log [OHâ»], and pH = Kw / [Hâº] do not correctly answer this question because they either refer to different concepts, describe properties of other molecules or processes, or represent common misconceptions about this topic.
