Answer 2

The chemical equation for the reaction between Na2SO3 and CaSO3 in the presence of NaOH can be written as:

2 Na2SO3 + CaSO3 + 2 NaOH → 2 NaOH·CaSO3 + SO2 + H2O

In this reaction, NaOH acts as a catalyst, and the products are sodium-calcium-sulfite, sulfur dioxide, and water. The reaction can be balanced by ensuring that the number of atoms of each element is the same on both sides of the equation. The balanced equation is:

2 Na2SO3 + CaSO3 + 4 NaOH → 2 Na2Ca(SO3)2·2H2O + 2 SO2

Note that the product, sodium-calcium-sulfite, is hydrated and has the formula Na2Ca(SO3)2·2H2O.
