Determine whether each of the following oxides is acidic, basic, or amphoteric. Use balanced chemical equations to support your answer.
(a) MgO (b) SO3 (c) Ga2O3 (d) Na2O (e) H2O (f) P4O10
Homework Answers
MgO - basic oxide
MnO + 2HCl → MnCl2 + H2O
SO3 - Acidic oxide
SO3 (g) + H2O (l) → H2SO4 (aq)
Ga2O3 - amphoteric
Ga2O3 + 6 HCl → 2 GaCl3 + 3 H2O
Ga2O3 + 2NaOH + 3H2O → 2Na[Ga(OH)4]
Na2O - basic
Na2O + H2O → 2 NaOH
H2O- amphoteric
H₂O + NH₃ → OH- + NH₄+
H₂O + HCl → H₃O+ + Cl-
P4O10 - acidic
P4O10 + 6 H2O → 4 H3PO4
