Carboxylic acids have many properties and reactions in common with mineral acids, such as hydrochloric and sulfuric acid. What is different is that they are weak acids, so react more slowly and have higher pHs (but still less than 7).
The smaller carboxylic acids are water-soluble, and ethanoic acid has a surprisingly high melting and boiling point. These features are due to their abilities to form hydrogen bonds. Ethanoic acid forms hydrogen bonds in a special way, forming dimers (di = two; mer = unit). As a dimer, ethanoic acid has a larger electron cloud, so can have a higher extent of intermolecular bonding.
The experiment on p135 was done and filmed. Sadly, it didn't go very well, so Mr Nicoll re-filmed it:
