Chemistry AQA AS EMPA 2010?

My brief is 'to investigate the compound present in a glass cleaner by means of the determination of the enthalpy change of neutralisation and a series of observation exercises'

I've already done the first task which the enthalpy of neutralisation, and I have my task 2 next week. But the thing is my teacher didn't really explain what would be on task 2 except that its observation tests.What do you think I should revise for this? Tests for group 1 or halogens or stuff like tests for co2 or hydrogen?
Thanks :)
