Answer 1

H3PO4 = H(+) + H2PO4(-)
H2PO4(-) <=> H(+) + HPO4(2-)
HPO4(2-) <=> H(+) + PO4(3-)

Answer 2

Equation of Stepwise Dissociation

The equation of stepwise dissociation for a compound like phosphoric acid (H3PO4) can be represented as follows:

1. Step 1: H3PO4 = H(+) + H2PO4(-) 2. Step 2: H2PO4(-) = H(+) + HPO4(2-) 3. Step 3: HPO4(2-) = H(+) + PO4(3-) 4. Overall Equation: H3PO4 = 3H(+) + PO4(3-) [[1]](https://uchi.ru/otvety/questions/napishite-uravnenie-dissotsiatsii-fosfornoy-kisloty)

This equation illustrates the stepwise dissociation of phosphoric acid into its respective ions.
