AS OCR chemistry assessment tomorrow.

Showing 1 to 2 of 2

Hi, I have a qualitative chemistry assessment tomorrow and I have no idea what to revise. All I know is that it is on acid and reactions and the practical we are doing is about identifying 4 unknown solutions. I was thinking it might be the halide tests but we have already done assessment on that. Maybe the silver nitrate solution test? 

It would be great if anyone would let me know what it is about if they have already done this assessment.

Have you done the AS Qualitative on reaction rates and enthalpy change? if you have is there any chance you'd tell me what's on it?
