Give balanced equation for the action of sulphuric acid on each of the following:
1) Potassium hydrogen carbonate
2) Sulphur
1) KHCO3 +H2SO4 (<2000C) --> KHSO4 +H2O+CO2
2) S+2H2SO4 --> 3SO2 +2H2O
In the contact process for the manufacture of sulphuric acid give the equation for the conservation of sulphur trioxide to sulphuric acid.
SO3 +H2SO4 --> H2S2O7 (oleum)
H2S2O7 + H2O -->2H2SO4
Write balanced equation for the following :
Action of concentrated sulphuric acid on carbon.
C + Conc. 2H2SO4 -----> CO2+2H2O +2SO2
