POST-LAB REPORT FOR THE SOLUBILITY EXPERIMENT

I) Conclusion: Write the conclusions regarding your observations and results obtained from each part 2A, 2B, 2C, and 2D, separately. Separately describe and explain in your conclusions whether the experimental observations and results obtained from that part enabled you to confirm the solubility behavior of various compounds based upon what you had
