Which of the following statements are true for the reactions that precede them.?

Question

NOTE: Read the equations left to right

a) H2PO4 − + H2O ↔ HPO4 2− + H3O + H2PO4 &minus is the Lewis acid


b) HClO4 + H2O → H3O + + ClO4 − HClO4 is the Lewis base


c) H2PO4 − + H2PO4 − ↔ H3PO4 + HPO4 2− H2PO4 &minus is both the Lewis base and the Lewis acid


d) HCl + H2O → H3O + + Cl − Water is the Lewis base


e) Fe(H2O)6 3+ + H2O ↔ Fe(H2O)5(OH) 2+ + H3O + Fe(H2O)6 3+ is the Lewis acid

i got it, ACDE

Answer 1

Yes, you're right: a, c, d and e.
