Answer #1

1. According to Pauling rule for the pk1 value, the compounds having more oxo groups have less pk1 value and will be the strong acid in nature.

pKa= (8-5p), where P is the number of oxo groups attach to the central metal atom.

Therefore,

- (1) HR Ou (2) H₂ 5604 0-4 86-0-H Ro- o o pka = (8-5p) = (8 - 5X 93) = -70 Hol lo pka = (8-5p) = (8- 5x2) = (8-10) = -2 (3)

The order of acid strength is

1>2>4>3

b. u As2O3 : It is an ampho teic salt As₂O₃ + H₂O - H₃ As Oz (2) TeO₂: Amphoteric TeO ₂ + H₂O - H₂ Te O3
