Options

  1. AH 3 O + , H 2 P O 4 - , H C O 3 -
  2. BH 2 O , H P O 4 2 - , H 2 P O 2 -
  3. CH 2 O , H 2 P O 4 - , H P O 4 2 -
  4. DH C 2 O 4 - , H 2 P O 4 - , S O 4 2 -

Correct answer

C. H 2 O , H 2 P O 4 - , H P O 4 2 -

Step-by-step solution

Amphoteric species can behave like acids and base i.e. it can donate and accept H + ion.
