प्रश्न
What happens when ethanoic acid reacts with sodium hydroxide? Write equation of the reaction involved.
Write chemical equation for the reaction of ethanoic acid with sodium hydroxide.
उत्तर
The reaction between ethanoic acid \[\ce{(CH3COOH)}\] and sodium hydroxide \[\ce{(NaOH)}\] is a neutralisation reaction:
\[\ce{CH3COOH + NaOH → CH3COONa + H2O}\]
In this equation, ethanoic acid reacts with sodium hydroxide to produce sodium acetate \[\ce{(CH3COONa)}\] and water \[\ce{(H2O)}\]. This is a typical acid-base neutralization process, where an acid combines with a base to form salt and water.
