प्रश्न
Give one equation to show the following properties of sulphuric acid : Dehydrating property
उत्तर
Dehydrating property of sulphuric acid:
\[\ce{H2SO4}\] has a great affinity for water, and therefore, it acts as a dehydrating agent.
\[\ce{HCOOH ->[conc.H2SO4] CO + H2O}\]
\[\ce{C2H5OH ->[conc.H2SO4] C2H4 + H2O}\]
