SOLUBILIDAD Y DENSIDAD

Physical Properties of Technical Compounds

Introduction to Experiment

• The experiment focuses on studying the physical properties of technical compounds, specifically solubility and density. Each test tube is assigned a specific substance for analysis.

Initial Setup

• A total of 12 liters of a solution is prepared, including benzene and a pinch of salt, to observe their interactions in the first batch of test tubes.

• An inorganic solvent is introduced into the first set of test tubes while an organic solvent is added to the second set for comparison.

Observations on Solubility

• The initial three test tubes contain organic substances that do not dissolve in water, leading to the formation of two distinct phases: one floating (organic) and one settled at the bottom (aqueous).

• It can be concluded that less dense compounds remain afloat, as observed with salt in tube four which does not dissolve due to its natural properties.

Analysis of Results

• The organic solvents like gasoline and ether do not dissolve with water; thus, they maintain their separate phase within the mixture. This indicates their non-polar nature compared to polar solvents like water.

• The experiment highlights how certain organic solvents fail to dissolve samples effectively, resulting in a layered system known as "genius." This emphasizes the importance of solvent choice in chemical reactions.
