For each mole of H3PO4 and of Na2HPO4 mixed in aqueous solutions:
a. 2 mols of H2PO4- are formed
b. 1 mol of H2PO4- is formed
c. No reaction occurs
Homework Answers
H3PO4 acts as an acid and HPO42- acts as a base when the two are mixed as per following reaction equation:
H3PO4 + HPO42- ------> 2H2PO4-
This means when one mole each of H3PO4 and HPO42- are combined, two moles of H2PO4-are formed.
Thus answer is option a.2 mols of H2PO4- are formed.
Comment in case of any doubt.
