An alcohol and a carboxylic acid salt (carboxylic acid if protonated at end of reaction).
Formic acid is methanoic acid. A carboxylic acid.
The carboxylic acid group or -COOH group makes it acidic
A fatty acid salt is a kind of carboxylic acid salt. But not all carboxylic acid salts are fatty acid salts.
Vinegar is ethanoic acid CH3COOH, so yes it is a carboxylic acid.
the carboxylic group normally came from carboxylic acid. Hence, the carboxylic acid is polar acid. and the polarity came from the carboxylic group for that it is hydrophilic group
Vinegar is dilute acetic acid and thus contains a carboxylic acid.
It depends on witch carboxylic acid you mean, there are thousands carboxylic acids.
Tartaric acid
carboxylic acid
Ethanoic acid
When carboxylic acid react with metal gives Salt and hydrogen
