Qualitative Analysis and Final Exam Unit 9

For the last few weeks of school we will be working on qualitative analysis of unknown solutions.  This extended lab will summarize many of the reaction types we have studied this year and will increase student analytical skills.

The final exam will be comprehensive.  Students should review all notes from the year, study chapter reviews and complete a practice exam during the last days before the final exam.
