Chapter 15: Problem 90

Consider the neutralization reaction that occurs upon the reaction of aqueous potassium hydroxide with aqueous hydrochloric acid. (a) Write a complete ionic equation for this neutralization reaction. (b) Write a net ionic equation for this neutralization reaction.

Short Answer

Expert verified
The complete ionic equation for the neutralization reaction between aqueous potassium hydroxide and aqueous hydrochloric acid is: \(K^+(aq) + OH^-(aq) + H^+(aq) + Cl^-(aq) \rightarrow K^+(aq) + Cl^-(aq) + H_2O(l)\). The net ionic equation for this reaction is: \(H^+(aq) + OH^-(aq) \rightarrow H_2O(l)\).

Step by step solution

01

1. Balanced Chemical Equation

To begin, we need to write the balanced chemical equation for the neutralization reaction between aqueous potassium hydroxide (KOH) and aqueous hydrochloric acid (HCl). In a neutralization reaction, an acid (HCl) reacts with a base (KOH) to produce water (H_2O) and a salt (KCl). The balanced equation for the reaction is: KOH(aq) + HCl(aq) → KCl(aq) + H_2O(l)

2. Complete Ionic Equation

Next, we need to write the complete ionic equation. To do that, we'll break apart the aqueous species, KOH(aq) and HCl(aq), into their respective ions according to their solubility in water. The complete ionic equation is: K^+(aq) + OH^-(aq) + H^+(aq) + Cl^-(aq) → K^+(aq) + Cl^-(aq) + H_2O(l)

3. Net Ionic Equation

Now, lastly, we need to write the net ionic equation. To write the net ionic equation, remove any spectator ions that don't participate in the reaction. In this case, potassium ion (K+) and chloride ion (Cl-) are spectator ions, as they remain the same on both sides of the equation. The net ionic equation is: H^+(aq) + OH^-(aq) → H_2O(l)
