What is the function of the wet paper towel condenser
to prevent reactants and products escaping from the reaction vessel in vapour form
Why is a water bath used rather than a bunsen burner
some of the reactants and products are flammable
What role does the concentrated sulfuric acid play
acts as a catalyst
What is the purpose of the sodium hydrogencarbonate solution
To neutralise the concentrated sulfuric acid and any unreacted carboxylic acid
State two pieces of evidence which suggested that an ester has been formed
a distinctive smell an oily later on the surface of the sodium hydrogencarbonate solution
What happens when esters go through hydrolysis
reacts with water to produce an alcohol and a carboxylic acid
What can esters be used for
can be used as solvents for non polar compounds that do not dissolve in water
Explain why a step is described as a condensation reaction
it has two molecules joining together with the loss of a water molecule
Suggests why when making esters the reaction mixture must be kept below a certain temperature
to prevent boiling off of the alcohol
What esters are formed form the condensation of glycerol and three carboxylic acid
edible fats and edible oils
What can the average kinetic energy of the particles in a substance be measured
Thermometer
