Question

Complete the balanced neutralization equation for the reaction below. Be sure to include the proper phases for all species within the reaction. HCl(aq) + NaOH(aq)

Answer 1

In a neutralization reaction between HCl and NaOH, the balanced molecular equation is HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l). The net ionic equation simplifies to H+(aq) + OH−(aq) → H₂O(l), indicating the formation of water as the hydrogen and hydroxide ions react.

Step-by-step explanation:

The neutralization reaction between hydrochloric acid and sodium hydroxide can be represented by the balanced molecular equation:

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

The complete ionic equation for this reaction, showing the dissociated ions, is as follows:

H+(aq) + Cl−(aq) + Na+(aq) + OH−(aq) → Na+(aq) + Cl−(aq) + H₂O(l)

From this, the net ionic equation is derived by canceling out the spectator ions, leaving:

H+(aq) + OH−(aq) → H₂O(l)

This equation reflects the core process in which a hydrogen ion and a hydroxide ion combine to form water.

Answer 2

The balanced molecular equation for the neutralization reaction of HCl and NaOH is HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l). The complete ionic equation is H+(aq) + Cl⁻(aq) + Na+(aq) + OH⁻(aq) → Na+(aq) + Cl⁻(aq) + H₂O(l), and the net ionic equation is H+(aq) + OH⁻(aq) → H₂O(l).

Step-by-step explanation:

The student's question involves completing a balanced neutralization equation. The balanced molecular equation for the reaction of hydrochloric acid (HCl) with sodium hydroxide (NaOH) is:

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

The complete ionic equation for this reaction is:

H+(aq) + Cl⁻(aq) + Na+(aq) + OH⁻(aq) → Na+(aq) + Cl⁻(aq) + H₂O(l)

Finally, the net ionic equation, which shows only the ions that participate in the formation of the products, is:

H+(aq) + OH⁻(aq) → H₂O(l)

This represents the neutralization of hydrochloric acid with sodium hydroxide, forming sodium chloride and water as products. The sodium and chloride ions are spectator ions and do not appear in the net ionic equation.
