Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

1. You are given a substance that is equally soluble in water and hexane (two immiscible solvents). a) What is K,? b) If you start with 10 g of the substance dissolved in 100 ml of water and are given 100 ml of hexane to extract with, algebraically show that it is better to do two smaller extractions using 50 ml of hexane for each extraction than it is to do one extraction using 100 ml of hexane.

4- The size of the crystals increase the melting point 5-High K value in extraction process means high solubility. 6-Aspirin is acetyl benzoic acid salt. 7-In recrystallization we must use a minimum amount of solvent to keep the loss of solute. 8-Using NaCl solution in saponification process will decrease the aggregation of the formed soap molecules 9-In extraction the ratio of the concentration of the two solutes is known equilibrium coefficient. 10- Boiling chips was used to increase the boiling point.
Materials Needed solid I2 solid CUSO4-5H20 food dye solid (NH4)2SO4 heavy metals waste container halogenated waste container non-halogenated waste container semi-micro test tubes and rack regular test tubes and rack squash pipettes acetone cyclohexane propan-2-ol Method Part A: Solubility of ionic and molecular solids 1. Place a small amount (about the size of 1 grain of rice, see picture) of copper sulfate into each of three DRY semi-micro test tubes. Add 20 drops of water to the first test tube and gently flick the test tube with your finger to ensure mixing. 2. Repeat step 1 using acetone in place of water as the solvent in the second test tube. 3. Repeat step 2 replacing acetone with cyclohexane in the third test tube. Hold the test tubes against a white background to compare the solubility of copper sulfate in the three solvents and record your results. Discard these mixtures into the heavy metals waste container in the fume cupboard. Once these test tubes have been emptied you…
