Using the Acid Dissociation Constants for Glycine (K_a1 = 4

Using the acid dissociation constants for glycine (K_a1 = 4.6 × 10−³ and K_a2 = 2.5 × 10−¹⁰) ,calculate the [Z]/[C⁺] ratio at pH 8.00.(Z = Zwitterion,C⁺ = fully protonated cation)

A) 2.2 × 10−⁶
B) 6.6 × 10−⁴
C) 2.5 × 10−²
D) 4.0 × 10¹
E) 4.6 × 10⁵
