Problem
A student prepares two 1.0 L phosphate buffers, each with a total concentration of 0.40 M in conjugate pair but different component ratios.
• Buffer C: 0.30 M H₂PO₄⁻ and 0.10 M HPO₄²⁻
• Buffer D: 0.10 M H₂PO₄⁻ and 0.30 M HPO₄²⁻
Which buffer will be more effective at neutralizing an added strong base, and why? Provide your answer in one concise sentence.
