Because the oxide ion is basic, metal oxides react readily with acids.
(a) Write the net ionic equation for the following reaction:
(b) Based on the equation in part (a), write the net ionic equation for the reaction that occurs between NiO(s) and an aqueous solution of nitric acid.
(a)
Given reaction is as follows:
FeO(s) + 2HClO4(aq) → Fe(ClO4)2(aq) + H2O(l)
Total ionic equation is,
FeO(s) + 2H+(aq) + 2ClO-4(aq) → Fe2+(aq) + 2ClO-4 (aq) + H2O(l)
Net ionic equation is,
FeO(s) + 2H+(aq) → Fe2+(aq) + H2O(l)
(b)
Reaction between NiO(s) and HNO3(aq) is as follows,
NiO(s) + 2HNO3(aq) → Ni(NO3)2(aq) + H2O(l)
Net ionic equation is,
NiO(s) + 2H+(aq) → Ni2+(aq) + H2O(l)
(a)
Given reaction is as follows:
FeO(s) + 2HClO4(aq) → Fe(ClO4)2(aq) + H2O(l)
Total ionic equation is,
FeO(s) + 2H+(aq) + 2ClO-4(aq) → Fe2+(aq) + 2ClO-4 (aq) + H2O(l)
