Dissolving Of Solutes Lab Report
Purpose
The goal of the investigation was to observe if certain solutes would result in dissolving in different solvents. Solubility is what determines if a substance will dissolve in a certain solvent. The ionic solutes will dissolve into the polar solvents and the covalent solutes will dissolve into the non-polar solvents because the molecules of the solvents have a stronger force that will break apart the solute and dissolve it into the solvent.
Procedure
Small amount of the solutes, roughly one scoop from the scoopula, were placed into clean test tubes. 2-3 pipettes of the solvent were placed on to the solutes. They were placed onto a tray and were left to dissolve over time. Obsevations were taken of each solution mixture.

Borax, sodium phosphate, and ammonium chloride, are all ionic compounds. This can be shown based on the electronegativity difference between the atoms, and the fact that it involves metals and non metals. The rest of the solutes are covalent bonds. Iodine and paraffin are both non polar molecules. This can be shown by the eletronegativity difference, and the shapes the molecules make, which show that they are very balanced molecules. Sugar, citric acid, urea, and borax, are all polar bonds. This is known because they have a bigger electronegativity difference than non polar, but smaller than ionic bonds. Also, the shapes of the molecules show the …show more content…
This reasoning is not supported by the lab. Based on the lab’s evidence, the things that need to be accounted for are not just ionic or covalent bonding, but also polar and non polar substances. If this hypothesis was correct, the citric acid should have dissolved in hexane, and not in dissolved in water, but instead it did the opposite. The solutes that would dissolve in acetone would be the sodium phosphate, ammonium chloride, sugar, citric acid, urea, and
