Give a balanced equation for the following reaction of synthesis involving the formation of:
An acid – from sulphur dioxide gas
Advertisements
उत्तर
Acid from sulphur dioxide gas.
\[\ce{SO2 + H2O->\underset{\text{sulphurous acid}}{H2SO3}}\]
OR
\[\ce{2SO2 + O2->\underset{\text{sulphur trioxide}}{2SO3}}\]
When `"SO"_3` is dissolved in water
\[\ce{SO3 + H2O->\underset{\text{sulphuric acid}}{H2SO4}}\]
OR
Oxidation of aqueous solution of sulphur dioxide with oxygen.
\[\ce{2SO2 + 2H2O + O2->2H2SO4}\]
