Effects of polarity of a molecule on solubility

hi how are you ?i need you to do a report for this Experiment not more then there pages. Question: How does the polarity of a molecule affect its solubility? Goals Objectives Introduction Background: Solutions are homogeneous mixtures consisting of at least two substances. The substance present in the larger amount is the solvent and the substance present in lesser amount is the solute. We are most familiar with solutions in which the solvent is a liquid and that’s what we will examine in this experiment. However the solvent can also be a gas as is the case with air or a solid in an alloy such as brass. When two liquids mix completely we use the term miscible rather than soluble. Two liquids that do not mix are immiscible. The polarity of a molecule plays an important role in its physical properties such as solubility. A general rule of thumb is “like dissolves like.” Polar solutes will typically be soluble in polar solvents and non-polar solutes will be soluble in non-polar solvents. Since ionic compounds dissociate when they dissolve they will dissolve best in solvents that are capable of stabilizing the charge on the ions. Because of this polar solvents (which have a permanent dipole capable of interacting with dissolved ions) will dissolve ionic compounds whereas non-polar solvents will not. In this experiment you will predict the polarity of a series of different compounds and then obtain experimental evidence that you can use to support or refute your prediction.
