Answer

To solve the given reaction \( H_4P_2O_7 + H_2O \rightarrow 2H_3PO_4 \), we need to analyze the reactants and products to determine the type of reaction and the nature of the product formed.

### Step-by-Step Solution:

**Step 1: Identify the Reactants and Products**
- The reactants are \( H_4P_2O_7 \) (pyrophosphoric acid) and \( H_2O \) (water).
- The product formed is \( H_3PO_4 \) (phosphoric acid).

**Step 2: Determine the Type of Reaction**
- This reaction involves the addition of water to a compound, resulting in the formation of another compound. This is characteristic of a hydrolysis reaction.
- Hydrolysis reactions typically involve the breakdown of a compound by the addition of water.

**Step 3: Analyze the Product**
- The product \( H_3PO_4 \) is known as phosphoric acid.
- To confirm that it is an oxyacid, we need to check the definition of an oxyacid:
- An oxyacid contains hydrogen, oxygen, and at least one other element (in this case, phosphorus).
- It must have hydrogen atoms bonded to oxygen atoms that can dissociate to form \( H^+ \) ions.

**Step 4: Verify the Oxyacid Characteristics**
- \( H_3PO_4 \) has:
- 3 hydrogen atoms (H)
- 4 oxygen atoms (O)
- 1 phosphorus atom (P)
- The structure of \( H_3PO_4 \) includes three hydroxyl (–OH) groups, which can release \( H^+ \) ions when dissociated.

**Step 5: Conclusion**
- Since \( H_3PO_4 \) meets the criteria of being an oxyacid, and specifically has the "ic" suffix, we conclude that the correct option is that the product is an oxyacid with the "ic" suffix.

### Final Answer:
The reaction \( H_4P_2O_7 + H_2O \rightarrow 2H_3PO_4 \) produces phosphoric acid, which is an oxyacid with the "ic" suffix.
