Carboxylic Acids

• Carboxylic acids contain the carboxyl functional group (-COOH)
• Carboxylic acids are saturated
• Carboxylic acids can be represented by the general formula: $C_nH_2n+$$1COOH$
• Carboxylic acids solubility decreases as carbon chain length increases
• Carboxylic acids melting and boiling points increases as chain length increases, due to stronger intermolecular forces
• Carboxylic acids are used in the preparation of preservatives, soaps, and medicines
• Vinegar, a solution of ethanoic acid, with molecular formula $CH_3COOH$, is used in household products, as it's a non-toxic acid, so can be used safely in household situations
• Carboxylic acids can react with metals, metal oxides, hydroxides, and carbonates, forming salts.

  Ethanoic acid -> (metal) ethanoate

  Propanoic acid -> (metal) propanoate
