Answer 2

Dehydrating agent

Explanation:

Ethanol can be dehydrated to give ethene by heating it with an excess of concentrated sulphuric acid at about 170°C.  

The function of sulphuric acid in this reaction is as a dehydrating agent.

Concentrated phosphoric (V) acid, H3PO4, can also be used for this purpose, instead of sulphuric acid. The acids aren't written into the equation because they serve as catalysts.

C2H5OH -----Con. H2SO4---> C2H4 + H2O
