What is the chemical test to differentiate ethanol from ethanoic acid

We can distinguish between ethanol and ethanoic acid by reacting them with a metallic carbonate like Na2CO3 or a bicarbonate like NaHCO3 ethanoic acid reacts to give to give CO2 and no reaction takes place in case of ethanol.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
