Question

Write chemical reactions for different steps in the manufacture of sulphuric acid by lead chamber process. Draw the structure of phosphours pentachloride.

Answer 1

Manufacture of sulphuric acid :
Lead chamber process :
Step I : `2H_(2)O+NO rarr HNO_(3)+3H^(+)`
Step II : `S+O_(2) rarr SO_(2)`
Step III : `2HNO_(3)+2SO_(2) rarr H_(2)O+NO+NO_(2)+2SO_(3)`
OR
`SO_(2)+NO_(2) rarr SO_(3)+NO`
Step IV : `SO_(3)+H_(2)O rarr H_(2)SO_(4)`
Net reaction : `2SO_(2)+O_(2)+2H_(2)O overset("NO")rarr 2H_(2)SO_(4)`
Structure of `PCl_(5)`:

Hybridisation : `sp^(3)d`
Shape : Trigonal bipyramidal
