Write the reaction equation: S-SO2-H2SO3-K2SO3-SrSO3
| September 11, 2021 | education
Let’s carry out the following chain of transformations: S – SO2 – H2SO3 – K2SO3 – SrSO3.
S + O2 = SO2.
When sulfur reacts with oxygen, the result is sulfur oxide.
SO2 + H2O = H2SO3.
When sulfur oxide and water interact, the result is sulphurous acid.
H2SO3 + 2KOH = K2SO3 + 2H2O.
When sulfurous acid and potassium hydroxide react, the result is potassium sulfite and water.
К2SO3 + Sr (OH) 2 = SrSO3 + 2 KOH.
When potassium sulfite and strontium hydroxide interact, the result is strontium sulfite and potassium hydroxide.
