Verified step by step guidance1
Step 1: Understand the naming and composition of hydrophosphoric acid. Hydrophosphoric acid is another name for phosphoric acid, which is a common oxyacid of phosphorus.
Step 2: Recall the general formula for phosphoric acid. Phosphoric acid contains phosphorus (P), oxygen (O), and hydrogen (H) atoms arranged in a specific ratio.
Step 3: Recognize that phosphoric acid has three acidic hydrogen atoms attached to oxygen atoms bonded to phosphorus, giving it the formula \(\mathrm{H_3PO_4}\).
Step 4: Compare the given options with the known formula for phosphoric acid. The correct formula should have 3 hydrogens, 1 phosphorus, and 4 oxygens, matching \(\mathrm{H_3PO_4}\).
Step 5: Conclude that the correct chemical formula for hydrophosphoric acid is \(\mathrm{H_3PO_4}\).
