Question

Double replacement: NaOH(aq) HCl(aq)→ _____ _____ Express your answer as a chemical equation. Your answer does not need to include the phases of the product(s).

Answer 1

Answer:

NaOH + HCl → NaCl + H₂O

Explanation:

In double replacement reactions, we have 2 ionic compounds that exchange their cations and anions. Let's write the ionic equation for the reactants.

Na⁺(aq) + OH⁻(aq) + H⁺(aq) + Cl⁻(aq) →

Cl⁻(aq) will replace OH⁻(aq) in NaOH forming NaCl(aq), and OH⁻(aq) will replace Cl⁻(aq) in HCl forming H₂O(l). The resulting chemical equation is:

NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
