H₂SO₃ + BaCO₃ reaction has the following intermolecular forces,

• H₂SO₃ is covalent compound and shows van der Waals forces because of weak electrostatic forces of attraction in molecule.
• BaCO₃ is ionic in nature, so it possesses intermolecular forces of attraction.

H₂SO₃ + BaCO₃ reaction enthalpy

H₂SO₃ + BaCO₃ reaction enthalpy is -1362.12 KJ/Mol. Enthalpies of each compound that is a reactant or a product in the reaction are as follows.

Enthalpy change for reaction between H₂SO₃+ BaCO₃, Calculated by these formulae.

Change in enthalpy = addition of enthalpies of formation of product – addition of enthalpies of formation of reactant.

Enthalpy change = [(7.12) + ( -280.7) + (- 393.5)] – [( -814.4) + ( -1214.8)]

                            = -2029.2 – (-667.08)

                            = -2029.2 + 667.08

                            = -1362.12 KJ/Mol

Is H₂SO₃ + BaCO₃ a buffer solution

H₂SO₃ + BaCO₃ is a buffer solution. As a result of the reaction between a weak acid and a strong base, barium sulfite salt is produced, resulting in an acidic buffer.

Is H₂SO₃ + BaCO₃ a complete reaction

H₂SO₃ + BaCO₃ is not complete reaction. The formation of barium sulfite salt makes the reaction irreversible in nature. However, H₂SO₃ being weak acid cannot undergo 100% dissociation.

Is H₂SO₃and BaCO₃ an exothermic or endothermic reaction

Reaction between H₂SO₃ and BaCO₃ is exothermic in nature, because heat is evolved during reaction. In order for the reaction to proceed, more energy must be absorbed than is released when salt is formed.

Is H₂SO₃ + BaCO₃a redox reaction

H₂SO₃ + BaCO₃  is not redox reaction. There is no change in oxidation state of any element (H, S, Ba, O, and C). Oxidation state has been maintained throughout the course of reaction.

Is H₂SO₃+ BaCO₃a precipitation reaction

H₂SO₃ + BaCO₃ is a precipitation reaction, because of formation of white precipitate of barium sulfite, which is insoluble in water, alcohol even in sulfurous acid.

Is H₂SO₃+ BaCO₃an irreversible reaction

H₂SO₃ + BaCO₃ is irreversible reaction. Formation of barium sulfite salt leads to white precipitate, thus reaction cannot be revert back forming reactant.

Is H₂SO₃ + BaCO₃a displacement reaction

H₂SO₃ + BaCO₃ is double displacement reaction. Ions of both reactants displace each other to form new barium sulfite, carbon dioxide and water.

Conclusion
