carboxylic acids

Cards (4)

    • the first four carboxylic acids are:
    • methanoic acid
    • ethanoic acid
    • propanoic acid
    • butanoic acid
    • carboxylic acids react with carbonates
    • they produce salt, water and carbon dioxide
    • salt ends in -anoate
    • e.g ethanoic acid + sodium carbonate -> sodium ethanoate + water + carbon dioxide
    • carboxylic acids can dissolve in water
    • they ionise and release H+ ions, so acidic solution produced
    • they do not ionise completely, so, form weak acidic solutions
    • have higher pH
    • carboxylic acids can reat with alcohols to form esters
    • an acid catalyst is used
    • water is produced
    • e.g ethanoic acid + ethanol -> ethyl ethanoate + water
