Final answer:
The balanced neutralization reactions for HCl with NaOH, HNO₃ with KOH, and CH₃COOH with NaOH produce water and a salt. The net ionic equations for these reactions demonstrate that H+ ions from acids react with OH- ions from bases to form water.
Step-by-step explanation:
To complete and balance the equations for the following acid-base neutralization reactions, we consider the fact that these reactions typically involve an acid reacting with a base to produce a salt and water. Here are the balanced reactions for the given examples:
a) HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
b) HNO₃(aq) + KOH(aq) → KNO₃(aq) + H₂O(l)
c) CH₃COOH(aq) + NaOH(aq) → CH₃COONa(aq) + H₂O(l)
We can further represent these reactions using ionic equations when applicable. For strong acids and bases that are completely ionized in water, the full ionic and net ionic equations highlight the actual species that react. For example, in the reaction between HCl and NaOH:
Full Ionic Equation:
H+ (aq) + Cl⁻ (aq) + Na+ (aq) + OH⁻ (aq) → Na+ (aq) + Cl⁻ (aq) + H₂O (l)
Net Ionic Equation:
H+ (aq) + OH⁻ (aq) → H₂O (l)
In these neutralization reactions, water is always one of the products along with an ionic compound known as a salt.
