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.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
