Question

Помогите пжлст составьте полные и сокращенные ионные уравнения реакций взаимодействия so2 и h2so3 с водой, основными оксидами,основаниями,растворимыми солями.

Answer 1

SO2 + H2O = H2SO3
SO2 + H2O = 2H[+] + SO3[2-]

SO2 + CaO = CaSO3

SO2 + 2NaOH = Na2SO3 + H2O
So2 + 2Na[+] + 2OH[-] = 2Na[+]+ SO3[2-] + H2O
SO2 + 2OH[-]  = SO3[2-] + H2O

H2SO3 + MgO = MgSO3 + H2O

H2SO3 + MgCl2 = MgSO3 + 2Hcl
2H[+] + sO3[2-] + Mg[2+] + 2Cl[-] = MgSO3 + 2H[+] + 2Cl[-]
Mg[2+] + So3[2-] = MgSO3

H2SO3 + 2NaOH = Na2SO3 + 2H2O
2H[+] + SO3[2-] + 2Na[+] + 2OH[-] = 2Na[+] + SO3[2-] + 2H2O
2H[+] + 2OH[-] = 2H2O

Answer 2

Complete and Net Ionic Equations for the Reaction of SO2 and H2SO3 with Water

When SO2 (sulfur dioxide) reacts with H2SO3 (sulfurous acid) in water, it forms sulfurous acid and sulfite ions. The balanced chemical equation for this reaction is as follows:

Complete Ionic Equation: SO2 + H2O → H2SO3 H2SO3 → 2H+ + SO3^2-

Net Ionic Equation: SO2 + H2O → H2SO3 H2SO3 → 2H+ + SO3^2-

In the complete ionic equation, all the species that are present in the reaction are shown as ions. In the net ionic equation, only the species that undergo a change are shown.

Reaction of SO2 and H2SO3 with Basic Oxides

When SO2 reacts with basic oxides, such as calcium oxide (CaO) or sodium oxide (Na2O), it forms sulfites. The balanced chemical equation for the reaction of SO2 with CaO is as follows:

SO2 + CaO → CaSO3

Similarly, when H2SO3 reacts with basic oxides, it also forms sulfites. The balanced chemical equation for the reaction of H2SO3 with CaO is as follows:

H2SO3 + CaO → CaSO3 + H2O

Reaction of SO2 and H2SO3 with Bases

When SO2 reacts with bases, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH), it forms sulfites. The balanced chemical equation for the reaction of SO2 with NaOH is as follows:

SO2 + 2NaOH → Na2SO3 + H2O

Similarly, when H2SO3 reacts with bases, it also forms sulfites. The balanced chemical equation for the reaction of H2SO3 with NaOH is as follows:

H2SO3 + 2NaOH → Na2SO3 + 2H2O

Reaction of SO2 and H2SO3 with Soluble Salts

When SO2 reacts with soluble salts, such as sodium chloride (NaCl) or potassium nitrate (KNO3), it does not undergo a direct reaction. However, SO2 can react with certain soluble salts under specific conditions to form sulfites. For example, when SO2 reacts with sodium sulfite (Na2SO3), it forms sodium bisulfite (NaHSO3). The balanced chemical equation for this reaction is as follows:

SO2 + Na2SO3 + H2O → 2NaHSO3

Similarly, when H2SO3 reacts with soluble salts, it can also form sulfites. For example, when H2SO3 reacts with sodium sulfite (Na2SO3), it forms sodium bisulfite (NaHSO3). The balanced chemical equation for this reaction is as follows:

H2SO3 + Na2SO3 + H2O → 2NaHSO3
