Using chemical equations, show how the triprotic acid H3PO4 ionizes in water. Phases, such as (l) or (aq), are optional.

Im not sure, but are you asking for all three reactions with H20?

If so, I will provide the first two and I'll let you do the last one.

H3P04 + H20------> +^H2PO4 + H3O^+

H2PO4 + H20 ------> +^HPO4 + H30^+

The ionization of triprotic acid H3PO4 in water can be represented by three steps:

Step 1: Formation of the first hydrogen ion (H+):
H3PO4 + H2O ⇌ H3O+ + H2PO4-

Step 2: Formation of the second hydrogen ion (H+):
H2PO4- + H2O ⇌ H3O+ + HPO42-

Step 3: Formation of the third hydrogen ion (H+):
HPO42- + H2O ⇌ H3O+ + PO43-

Overall equation combining the three steps:
H3PO4 + 3H2O ⇌ 3H3O+ + PO43-

To show how the triprotic acid H3PO4 ionizes in water, we need to write out the chemical equations for each ionization step. H3PO4 is a triprotic acid, meaning it can release three hydrogen ions (H+) into water.

Step 1: Ionization of the first hydrogen ion (H+):
H3PO4 (aq) + H2O (l) ⇌ H3O+ (aq) + H2PO4- (aq)

In this step, one hydrogen ion is released from H3PO4 forming the hydronium ion (H3O+) and leaving behind the dihydrogen phosphate ion (H2PO4-).

Step 2: Ionization of the second hydrogen ion (H+):
H2PO4- (aq) + H2O (l) ⇌ H3O+ (aq) + HPO4^2- (aq)

In the second step, another hydrogen ion is released from the dihydrogen phosphate ion, forming the hydronium ion (H3O+) and leaving behind the monohydrogen phosphate ion (HPO4^2-).

Step 3: Ionization of the third hydrogen ion (H+):
HPO4^2- (aq) + H2O (l) ⇌ H3O+ (aq) + PO4^3- (aq)

In the final step, the last hydrogen ion is released from the monohydrogen phosphate ion, forming the hydronium ion (H3O+) and leaving behind the phosphate ion (PO4^3-).

(Note: The equilibrium arrows, ⇌, indicate that the reactions can occur in both directions, and the reaction may not go to completion.)

These equations demonstrate the ionization of each hydrogen ion in H3PO4, resulting in the formation of hydronium ions (H3O+) and the corresponding phosphate ions (H2PO4-, HPO4^2-, and PO4^3-).
