Buffer solutions that maintain certain levels of pH or acidity are widely used in biochemical experiments. One common buffer system uses sodium dihydrogenphosphate and sodium monohydrogenphosphate. What are the formulas of these two compounds? A)Na(HPO₄) and Na(HPO₄)₂ B)NaH₂PO₄ and Na₂HPO₄ C)Na₂H₂PO₄ and NaHPO₄ D)NaPO₄ and NaHPO₄ E)Na₂(HPO₄)₂ and Na₂(HPO₄)

Question

Quizplus · Accepted Answer

Sodium dihydrogenphosphate has the formula NaHSO4, and sodium monohydrogenphosphate has the formula Na2HPO4. The options with these formulas are B and C. However, in option C, there is an extra hydrogen ion (H+) that is not present in the original compounds. Therefore, the correct option is B, with the formulas: NaHSPO4 and Na2HPO4.
