    Is it possible to identify a carboxylic acid using mass spectroscopy or mass spectrometry. Apart from these two methods are there any other ways?

    I would say it's pretty hard to identify a carboxylic acid using mass spec. Infra-red spectroscopy would be the best way to identify a carboxylic acid

    Those 'two methods' are one and the same, and no, they will not tell you what functional groups you have. Fragmentation is not a reliable method.

    IR and NMR are both pretty diagnostic when it comes to carboxylic acids.

    Thanks for your reply , could i use Na2CO3 or NaHCO3 to test for a carboxylic acid?

    Yeah any carbonate will do, and C02 will be given off

    Note that that is a test for any acid, not just organic acids.

    Not with Phenol Although I guess you could classify that as more of an alcohol but it's still acidic

    Well of course it depends on the strength of the acid lol. And if we're being picky phenol is more of an enol than an alcohol
