Sodium hydrogen carbonate is a basic salt. Justify the statement . How is it converted into washing soda?
Answers
Hello here is your answer:
Explanation:
Sodium hydrogen carbonate (Na₂HCO₃) is a basic salt because it is made up of a weak acid and strong base.
Reaction: NH₃ + NaCl + H₂O + CO₂ → NH₄Cl + Na₂HCO₃
[Ammonia] + [Water] + [Carbon Dioxide] → [Ammonium Chloride] + [Baking Soda or Sodium hydrogen carbonate].
2NaHCO₃ →(heat) Na₂CO₃ + H₂O + CO₂
[Baking Soda] →(heat) [Sodium carbonate] + [Water] + [Carbon Dioxide]
You have seen above that sodium
carbonate can be obtained by heating baking soda; recrystallisation of
sodium carbonate gives washing soda. It is also a basic salt.
Na₂CO₃ + 10H₂O → Na₂CO₃.10H₂0
Hope it helps :)
Answer:
Answer. It is a salt produced by the neutralization reaction between a strong base (NaOH) and a weak acid (H2CO3), hence it is a basic salt. It is heated strongly to produce sodium carbonate. Sodium carbonate is recrystallized to produce washing soda.
