Question

Hat is the correct formula for silver dihydrogen phosphate?

a) AgH_2PO_4
b) Ag_2HPO_4
c) Ag(H_2PO_4)_2
d) Ag_3H_2PO_4

Answer 1

The correct formula for silver dihydrogen phosphate is AgH_2PO_4, balancing one Ag+ cation with one H2PO4- anion.

Step-by-step explanation:

The correct formula for silver dihydrogen phosphate is AgH_2PO_4. Silver forms a +1 cation (Ag+), and the dihydrogen phosphate anion has a formula of H2PO4-. To balance the charges and get a neutral compound, we need one Ag+ ion to balance one H2PO4- anion, resulting in the formula AgH2PO4.
