With reference to your notes, name two products that are formed in this reaction (sodium hydroxide + hydrochloric acid) and write down their chemical formulae.

Products Formed in the Reaction

When sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), a neutralization reaction occurs. This reaction produces two main products:

1. Sodium Chloride (Nacl): This is formed as a result of the combination of the sodium ions (Na⁺) from sodium hydroxide and the chloride ions (Cl⁻) from hydrochloric acid.

   • Chemical Formula: NaCl

2. Water (H₂O): This is formed when the hydroxide ions (OH⁻) from sodium hydroxide combine with the hydrogen ions (H⁺) from hydrochloric acid.

   • Chemical Formula: H₂O

Summary of the Reaction

The overall chemical reaction can be represented as follows:

$\text{NaOH} (aq) + \text{HCl} (aq) \rightarrow \text{NaCl} (aq) + \text{H}_2\text{O} (l)$

In conclusion, the two products formed in the reaction of sodium hydroxide and hydrochloric acid are sodium chloride (NaCl) and water (H₂O).
