In the lab final, students will be divided into two groups of 15.

1. Group Allocation:
   • The first 15 students of the first half (or second half) will enter the lab first.
   • Once they finish, the next 15 students will enter.
   • Each group will have 1 hour and 30 minutes to complete their tasks.
2. Experiment Selection:
   • Upon entering, there will be 15 shuffled exam papers on a table, flipped backward.
   • Each paper has an experiment name written in a corner.
   • Students will be called roll-wise to pick a paper, which determines their assigned experiment.
3. Experiment Distribution:
   • There will be (or might be):
     • 4 Na₂CO₃ + HCl Titration
     • 4 KMnO₄ + H₂C₂O₄ Titration
     • 4 Na₂S₂O₃ + K₂Cr₂O₇ Iodometry
     • 3 Heat of Solution experiments
   • Experiment tables are arranged randomly to ensure no two adjacent students get the same experiment.
   • Solution concentrations in burettes differ even for the same experiment.
4. Performing the Experiment:
   • First, write the Experiment Name and Data Table exactly as done in the rough sheets during lab classes.
   • Then, perform the experiment, complete the Data Table, do the calculations, and write the results.
5. Viva:
   • After finishing the exam, students will be called for viva.
   • Viva is mostly related to the assigned experiment and focuses on deep theoretical understanding about the experiment.
