When sodium reacts with Ethanol, it sinks and does not melt. Effervescence occurs and hydrogen gas is evolved.
At the end a clear solution of sodium ethoxide is left in the tube. This is shown by the following equation
Ethanol + sodium w Sodium Ethoxide + Hydrogen

2C2H5OH (l ) + 2Na (s) w 2C2H5ONa (aq) + H2(g)
Alkanols react with metals at the top of reactivity series e.g. (Ca, Na and K) to form metal Ethoxides and Hydrogen gas.
