Question

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.

Answer 1

(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)
