how would you distinguish experimentally between an alcohol and a carboxylic acid?

•An alcohol doesn't change the colour of litmus paper
•Alcohol such as ethanol reacts with sodium to form sodium ethoxide-
2CH3CH2OH+2Na—>2CH3CH2ONa+H2
•An carboxylic acid changes the colour of litmus paper form blue to red
•Carboxylic acid such as ethanoic acid reacts with NaOH-
CH3COOH+NaOH—>CH3COONa+H2O

Another answer :- we can distinguish between alcohol and carboxylic acid on the base s of their reaction with carbonates and hydrogen carbonates . carboxylic acid reacts with carbonates and hydrogen carbonate to evolve carbon dioxide gas which turn lime water milkly . On the other hand alcohols do not react with carbonates and hydrogen carbonates
Metal carbonate/metal hydrogen carbonate+carboxylic acid

An alcohol is a neutral organic compound whereas a carboxylic acid us acidic in nature. We can distinguish b/w an alcohol and a carboxylic acid by using sodium hydrogencarbonate as follows:
a. The organic compound which produces brisk effervescence on adding NaHCo3 due to evolution of carbon dioxide will be a carboxylic acid.
b. The organic compound which has no effect on the NaHCo3 will be an alcohol.
thank you so much @aaryaa45

Well...I think your answer is more meaningful than mine...Ok
Thankyou @aaryaa45
