Which of the correct statement for the given acids?

Which of the correct statement for the given acids?

  • A. Phosphinic acid is a diprotic acid while phosphonic acid is a monoprotic acid.
  • B. Phosphinic acid is a monoprotic acid while phosphonic acid is a diprotic acid
  • C. Both are triprotic acids.
  • D. Both are diprotic acids

Step-by-step solution

Phosphinic acid (H3PO2) has only one ionizable hydrogen (the O-H group), so it is monoprotic. Phosphonic acid (H3PO3) has two ionizable hydrogens (both O-H groups), making it diprotic.
