Question

sodium hydrogen carbonate is a basic salt justify this statement? how is it converting into washing soda? explain.

Answer 1

Explanation:

Sodium hydrogen carbonate is a basic salt because its parent base is strong(NaOH) and parent acid is weak(H2CO3).

it involves following reactions:-

NaHCO3 is heated to form Na2CO3 + H2O + CO2

then

Na2CO3 (crystallization)> Na2CO3.10H2O(washing soda)

OR

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 2

Answer:

Explanation:

Sodium hydrogen carbonate is a salt produce by the nutralization reaction of strong base i.e,NaOH with a weak acid i.e, H2CO3 (Carbonic acid).

Hence salt produce by it is a basic salt and NaHCO3 is a basic in nature

NAHCO3 is heated at high temperatures to dehydrate it to produce sodium carbonate(Na2CO3) .

Then Na2CO3 is made to react with weather to make it Na2CO3.10H2O i.e, Sodium carbonate decahydrate (Washing soda).

Then NaCO
