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

Ionic:\[2 H^+ (aq)+ SO_{4} ^{2-} (aq) + 2K^+ (aq) + 2OH^- (aq) \rightarrow SO_{4} ^{2-} (aq) + 2K^+ (aq) + 2H_{2}O (l)\]
Net Ionic\[2 H^+ (aq)+ 2OH^- (aq) \rightarrow 2H_{2}O (l)\]
The ionic equation includes all compounds involved in the reaction, while the net ionic involves only compounds in which a change of state is observed. Notice that in the ionic equation, the sulfate and potassium ions are both present in the aqueous phase on both sides of the equation, so they are "spectator ions" and are not included in the net ionic equation.

Try the second one yourself :)

Answer 2

The 2H2O (l) was cut off in the ionic equation, but it should be there on the right side as well.

Answer 3

For the net ionic equation, it said to check the coefficients.
