Q1Domain Verified
In the context of the "The Complete OAT Acid-Base Equilibrium Course 2026: From Zero to Expert!", which of the following statements best describes the impact of a common ion on the ionization of a weak acid, as emphasized in the "OAT General Chemistry: Acids and Bases Mastery Hub: The Industry Foundation"?
The presence of a common ion will increase the acid dissociation constant ($K_a$).
The presence of a common ion will shift the equilibrium to the left, decreasing the acid's ionization.
The presence of a common ion will have no effect on the acid's ionization due to the nature of equilibrium.
The presence of a common ion will shift the equilibrium to the right, increasing the acid's ionization.

According to the "OAT General Chemistry: Acids and Bases Mastery Hub: The Industry Foundation" and the advanced concepts covered in "The Complete OAT Acid-Base Equilibrium Course 2026", how does the buffer capacity of a solution change when the pH deviates significantly from the pKa of the weak acid component of the buffer?
Buffer capacity decreases only when the pH is lower than the pKa.
Buffer capacity increases as the pH moves further away from the pKa.
Buffer capacity is maximized when the pH is equal to the pKa and decreases as the pH deviates from it.
Buffer capacity remains constant regardless of the pH relative to the pKa.
Q3Domain Verified
In the advanced discussions of "The Complete OAT Acid-Base Equilibrium Course 2026", particularly concerning polyprotic acids as covered in the "OAT General Chemistry: Acids and Bases Mastery Hub", what is the most significant factor determining the pH of a solution of a polyprotic acid when only the first dissociation constant ($K_{a1}$) is significantly larger than the second ($K_{a2}$)?
The autoionization of water.
The contribution of the first dissociation step ($K_{a1}$) to the overall [H+] concentration.
The concentration of the conjugate base of the second dissociation step.
The contribution of the second dissociation step ($K_{a2}$) to the overall [H+] concentration.
