Write the neutralisation reaction between acids and bases in terms of the ions involved.
उत्तर
Let us consider an acid-base neutralisation reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) to give sodium chloride salt (NaCl) and water.
Equations involving ions:
Hydrochloric acid ionises in water as follows,
HCl(aq) → H+(aq) + Cl- (aq)
Sodium hydroxide ionises in water as
NaOH(aq) → Na+(aq) + OH-(aq)
Let us now combine both the reactions above.
Na+(aq) + Cl-(aq) + H+(aq) + OH-(aq) → NaCl(aq)+ H2O(l)
