Question

Write balanced ionic equations and net ionic equations for the following reactions.
Aqueous sulfuric acid is neutralized by aqueous potassium hydroxide.
Express your answer as an ionic equation. Identify all of the phases in your answer.
Aqueous magnesium hydroxide is neutralized by aqueous hydrochloric acid.

Express your answer as an ionic equation. Identify all of the phases in your answer

Answer 1

The ionic equation will be: 
Mg2+(aq) + 2OH-(aq) + 2H+(aq) + 2NO3-(aq) → Mg2+(aq) + 2NO3-(aq) + 2H2O(l) 
And the net ionic: 
2OH-(aq) + 2H+(aq) → 2H2O(l) 
a Balanced equation would be:
Mg(OH)2(aq) + 2HNO3(aq) → Mg(NO3)2 (aq) + 2H2O(l) 
Now  thsi si so because of the standard equation which is base plus acid=Salt plus water. We need to have in mindo that Mg(OH)2 is sparingly soluble in water and is aqueous mos of the times
