Chemistry · Various concepts of acids and bases (Arrhenius, Bronsted Lowry and Lewis) and their ionization, acid-base equilibria (including multistage ionization) and ionization constants
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.
