PART A (WEEK 1) - SOLUBILITY TESTS Organic compounds follow three interdependent rules of solubility: 1. The solubility of a solute (a dissolved substance) in a solvent (the dissolving medium) is the most important chemical principle underlying three major techniques you will study in the organic chemistry laboratory: crystallization, extraction, and chromatography. By the end of this lab, students should be able to: Properly use an analytical balance to measure mass. U Heat until you just see thermal gradients (wavy heat lines) or bubbles begin to form. For instance some molecules were polar, slightly polar, and non-polar. 24. Solubility is the ability of a solute to dissolve in a. 0001 g in your datasheet.
