A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7. For example when HCl (Hydrochloric acid), a strong acid, reacts with NaOH, a strong base, the resulting salt is sodium chloride and water.
Answer : Baking soda (NaHCO3) liberates carbon dioxide gas on heating, confirmed by passing it in lime water. Whereas on heating washing soda Na2CO3.10H2O water of crystallisation is given out, the salt becomes anhydrous.
Reaction:
2NaHCO3 → Na2CO3 + H2O + CO2
Na2CO3.10H2O → Na2CO3 + 10 H2O
