Using the acid dissociation constants for glycine (K_a1 = 4.6 × 10−³ and K_a2 = 2.5 × 10−¹⁰),calculate the [Z]/[A−] ratio at pH 7.00.(Z = Zwitterion,A− = deprotonated anion)

Question

Quizplus · Accepted Answer

At pH 7, the ratio [Z]/[A−] can be calculated using the Henderson-Hasselbalch equation for the second dissociation step, where pH = pKa2 + log([A−]/[Z]). Solving for [Z]/[A−] gives approximately 4.0 × 10².
