TRSodium sulfite and sulfuric acid reaction is a chemical field of knowledge, if not a certain understanding of the people, it will be very strange. In order to let everyone understand the reaction between sodium sulfite and sulfuric acid more clearly, the following Rongda Chemical introduces the principle, type and chemical equation of the reaction between sodium sulfite and sulfuric acid, for those who are interested in it.
Sodium sulphite and sulphuric acid reaction equation
H2SO4(concentrated) + Na2SO3 == Na2SO4 + H2O + SO2↑
The +4 and +6 valences of element S are adjacent to each other and do not undergo redox reactions. s does not have a +5 valence.
Complex decomposition reactions, strong acid H2SO4 to weak acid H2SO3
The reaction between sodium sulphite and sulphuric acid is the main method of preparing SO2 in the laboratory
Type of reaction between sodium sulphite and sulphuric acid
The type of reaction between sodium sulphite and sulphuric acid is a complex decomposition reaction type.
Principle of the reaction between sodium sulphite and sulphuric acid
The principle of making a weak acid from a strong acid is used.
For example, H2SO4 + Na2CO3 = Na2SO4 + H2O + CO2
H2SO4 + Na2SO3 = Na2SO4 + H2O + SO2 (laboratory production of SO2)
Excess sodium sulphite or exactly the right reaction: H2SO4 + Na2SO3 = Na2SO4 + H2O + SO2
Excess sulphuric acid: 2H2SO4 + Na2SO3 = 2NaHSO4 + H2O + SO2
The above is the introduction of sodium sulfite and sulfuric acid reaction equation_type_principle.
