Which of the following is tetrabasic acid?

Options

  1. AOrthophosphorus acid
  2. BOrthophosphoric acid
  3. CMetaphosphoric acid
  4. DPyrophosphoric acid

Correct answer

D. Pyrophosphoric acid

Step-by-step solution

H ₄ P ₂ O ₇ (pyrophosphoric acid) is tetrabasic because it gives four H ⁺ ions.
