- Pyrophosphoric acid
Show Solution
The Correct Option is D
Solution and Explanation
The question is about identifying the oxoacid of phosphorus that contains the highest number of oxygen atoms in its chemical formula. To solve this, we need to consider the chemical formulas of each given option:
- Pyrophosphorus acid - Its chemical formula is H_4P_2O_5. It contains 5 oxygen atoms.
- Hypophosphoric acid - Its chemical formula is H_4P_2O_6. It contains 6 oxygen atoms.
- Phosphoric acid - Its chemical formula is H_3PO_4. It contains 4 oxygen atoms.
- Pyrophosphoric acid - Its chemical formula is H_4P_2O_7. It contains 7 oxygen atoms.
Analyzing the number of oxygen atoms in each formula, Pyrophosphoric acid with the formula H_4P_2O_7 contains the highest number of oxygen atoms (7 oxygen atoms).
Thus, the correct answer is Pyrophosphoric acid which contains 7 oxygen atoms, the most among the given options.
