HCl + NaOH (Net ionic equation)?
A balanced chemical equation for the reaction of (NaOH + HCl) is –
Steps involved in writing a net ionic equation are –
- Write the complete ionic equation.
- Identify spectator ions.
- Cancel the spectator ions.
- Obtain the net ionic equation.
When NaOH reacts with HCl, then, NaOH dissociates into Na+ and OH– ions while HCl dissociates into H+ and Cl– on the reactant side. While on the product side, NaCl is also water soluble so it breaks down into Na+ and Cl– ions in the presence of H2O.
So the complete ionic equation for this reaction is:
⇒ Na+(aq) + OH– (aq) + H+(aq) + Cl–(aq) –> Na+(aq) + Cl–(aq) + H2O
By looking at the above reaction, we find, (Na+ and Cl–) are spectator ions, hence, canceling them and obtaining the net ionic equation.
|The net ionic equation of HCl + NaOH is –|
|⇒ H+(aq) + OH−(aq) → H2O(l)|
This net ionic equation shows that an acid-base neutralization reaction actually takes place between hydrogen (H+) and hydroxide (OH–) ions only.
