    • Functional group
      -COOH
    • 1st

      Methanoic acid
    • 2nd

      Ethanoic acid
    • 3rd
      Propanoic acid
    • 4th 

      Butanoic acid
    • What is the double bond in a carboxylic acid?
      C=O
    • What type of acids are carboxylic acids when dissolved in water?
      Weak
    • Why are CA weak acids in water?
      They only partially ionise in aqueous solution, so they have a higher pH than a strong acid
    • Type of reaction of CA in water
      Reversible
    • Because CA are weak acids, they have a higher pH than a strong acid
    • Products when CA reacts with metal carbonate
      Salt, CO2, water
    • CA reaction with alcohol
      Ester (+ water)
    • Why are esters really useful molecules?
      They often have a pleasant smell, so they are used a lot in foods
    • Ethanoic aci + ethanol <-(sulfuric acid catalyst)> ethyl ethanoate
    • Requirement for CA reaction with alcohol
      Sulfuric acid catalyst
    • Type of reaction with CA and alcohol
      Reversible
