Suppose an Aqueous Solution Initially Contains One Mole of Hydrochloric $\rightarrow$

question 93

Multiple Choice

Suppose an aqueous solution initially contains one mole of hydrochloric acid and one mole of ammonia.Which of the following statements best describes the solution once it comes to equilibrium?

• A)The solution is neutral because the ammonia neutralizes the hydrochloric acid.
• B)The solution is highly acidic due to the ionization of HCl: HCl(aq) \(\rightarrow\) H⁺(aq) + Cl^-(aq).
• C)The solution is slightly acidic due to the equilibrium NH₄⁺(aq) ⇄ NH₃ (aq) \(\rightarrow\) H⁺(aq).
• D)The solution is slightly basic due to the equilibrium NH₃ (aq)+ H₂O(l) ⇄ NH₄⁺ (aq) +OH^-(aq).
• E)The solution is slightly basic due to the equilibrium Cl^-(aq) + H₂O(l) ⇄ HCl(aq) +OH^-(aq).
