Topic 5b- Quantitative analysis (paper 1)

Question 1

What is a titration?

Answer 1

Titration is an experiment that allows you to see what volume of reactant is needed to react completely with another substance.

Question 2

Why might the actual yield of a reaction be less than the theoretical yield of a reaction?

Answer 2

• incomplete reactions
• practical losses during the experiment
• competing, unwanted side reactions

Question 3

What factors should be taken into account when choosing a reaction pathway?

Answer 3

• atom economy
• percentage yield (the higher the % yield, the less reactants are wasted → cheaper production)
• rate of reaction
• position of equilibrium (if the reaction is reversible)
