My teacher has been setting up lots of titrations with Na2S2O3! So, I guess it will come up in one of the variants, not sure which one though. We've also been doing lots of tests for anions and cations!
Lately, we haven't practised organic tests, so I'm guessing there weren't any compounds in the laboratory instructions which indicated this type of question.

Hope I've helped. But again, I don't know if you'll be doing the same variant as me!

Identification of cation and anion is a compulsory question!!! What about enthalpy change???
