Examiners report

There was a mistake on this question and it had to be annulled (39 marks paper). Grade boundaries were lowered accordingly. The x-axis was incorrectly labelled as “volume of weak acid” instead of “volume of strong base”. We sincerely apologize for this mistake which will be corrected before publication.
