Answer A) NaH2PO4 Na2HPO4 H2PO4HPO42- + + Na+ 2Na+ As dissociation continues value of Ka of conjugate base decrease. Thus a salt with higher Ka value will be NaH2PO4 and salt with lower Ka value would be Na2HPO4. http://www.coursehero.com/tutors-problems/Chemistry/8548075-You-are-given-a-salt-that-could-be-NaH2PO4-or-Na2HPO4-a-Explain-h/
