Question

Na2SO3 -> SO2 -> K2SO3 -> BaSO3

Answer 1

NA2SO3+HCI=H2O+SO2+NACI

SO2+K2O=K2SO3

K2SO3+BA(NO3)2=BASO3(осадок)+2KNO3

Answer 2

The chemical reactions you've written involve the conversion of sodium sulfite (Na2SO3) into sulfur dioxide (SO2), then to potassium sulfite (K2SO3), and finally to barium sulfite (BaSO3). Let's break down each step of the reaction:

1. Na2SO3 (Sodium sulfite) → SO2 (Sulfur dioxide) When sodium sulfite (Na2SO3) is heated or undergoes a chemical reaction, it decomposes into sulfur dioxide (SO2) gas and sodium oxide (Na2O).

2. SO2 (Sulfur dioxide) → K2SO3 (Potassium sulfite) The reaction between sulfur dioxide (SO2) and potassium oxide (K2O) or potassium hydroxide (KOH) can produce potassium sulfite (K2SO3).

3. K2SO3 (Potassium sulfite) → BaSO3 (Barium sulfite) Potassium sulfite (K2SO3) can undergo a metathesis reaction with barium nitrate (Ba(NO3)2) or any other soluble barium salt, yielding barium sulfite (BaSO3) and potassium nitrate (KNO3) or the corresponding soluble potassium salt.

Overall, the complete reaction can be represented as follows: Na2SO3 → SO2 → K2SO3 → BaSO3

Please note that chemical reactions can be influenced by reaction conditions (temperature, pressure, catalysts, etc.), and the specific reaction pathway might vary based on the actual experimental setup. Additionally, it's essential to handle and perform chemical reactions safely, considering the hazardous nature of some reactants and products.
