What is the chemical formula for hydrophosphoric acid?

• A. H3P
• B. H3PO4
• C. H3PO2
• D. H3PO3

Answer: (A)

Verified step by step guidance

1. Understand that hydrophosphoric acid is a binary acid, which means it consists of hydrogen and one other non-metal element, in this case, phosphorus.
2. Recall that binary acids are named using the prefix 'hydro-' followed by the root of the non-metal element and the suffix '-ic'.
3. Identify that the chemical formula for hydrophosphoric acid should only include hydrogen and phosphorus, without any oxygen atoms.
4. Recognize that the chemical formula for hydrophosphoric acid is H₃P, as it consists of three hydrogen atoms and one phosphorus atom.
5. Eliminate the other options (H₃PO₄, H₃PO₂, H₃PO₃) as they contain oxygen atoms, which are not present in hydrophosphoric acid.
