Answer 2

NaHCO3 to Na2SO4 Transformation Chain

The transformation chain from NaHCO3 to Na2SO4 involves several chemical reactions. Here's a detailed breakdown of the transformation:

1. NaHCO3 + HCl = NaCl + H2CO3 (CO2 + H2O): - The reaction of NaHCO3 with HCl results in the formation of NaCl and H2CO3, which further decomposes into CO2 and H2O [[2]](https://hti.urfu.ru/fileadmin/user_upload/site_15078/Kafedry/Analitiki/KHimicheskie_i_FKHAM._Sbornik_zadach.pdf).

2. NaHCO3 + NaOH = ? + ?: - The reaction of NaHCO3 with NaOH results in the formation of other compounds, but the specific products are not provided in the available search snippets.

3. Na2SO4 + H2O = NaOH: - Na2SO4 reacts with water to produce NaOH.

4. Na2SO4 + SO3 = Na2SO4 + H2O: - The reaction of Na2SO4 with SO3 results in the formation of Na2SO4 and H2O.

5. Na2O + SO3 = Na2SO4: - Na2O reacts with SO3 to produce Na2SO4.

6. NaHCO3 + NaOH = ? + ?: - The reaction of NaHCO3 with NaOH results in the formation of other compounds, but the specific products are not provided in the available search snippets.

7. Na2O + Cl2O7 = 2NaClO4: - Na2O reacts with Cl2O7 to produce 2NaClO4.

These reactions illustrate the transformation chain from NaHCO3 to Na2SO4, involving various chemical reactions and intermediate compounds.
