WebEthanol can be dehydrated to give ethene by heating it with an excess of concentrated sulphuric acid at about 170°C. Concentrated phosphoric (V) acid, H 3 PO 4, can be used instead. The acids aren't written into the equation because they serve as catalysts. If you like, you could write, for example, "conc H 2 SO 4 " over the top of the arrow.
