A) hydrogen bond B) rotational C) H₃PO₄ D) H₂PO₄^– E) HPO₄ ^2– F) disordered G) positive entropy H) negative entropy I) higher electronegativity J) insoluble K) tetrahedral arrangement L) acid M) base N) only partially ionized

Question

Quizplus · Accepted Answer

At pH = pK1 = 2.15, the phosphate buffer solution would have equal amounts of H3PO4 and H2PO4- because this is the point where the acid (H3PO4) and its conjugate base (H2PO4-) are in equilibrium.

Matching -A Phosphate Buffer Solution at PH = PK1 = 2.15

Matching -A Phosphate Buffer Solution at PH = PK₁ = 2.15
