Description

Part 1: Urea: Polar

Urea is likely to be soluble in water because Urea is Polar due to the lone pair electrons on the oxygen making it very willing to attach and combine with other atoms Test results: When combining the Urea with the distilled water it was soluble after stirring it for a while so yes our prediction was correct. Aswell when the Urea was mixed with the hexane, the Urea just sat at the bottom of the test tube and did not combine so it was not soluble, so yes our prediction was correct again.

Hexane: Non-polar

Hexane will not be soluble in water or urea because hexane is nonpolar, while urea and water are polar, and the like dissolves like rule tells us this will not work. Test results: The prediction was correct. Hexane was not soluble with water or urea when tested. The water and hexane stayed separated, and the urea remained a solid when in the hexane.

Water ( H2O) : Polar

Water is likely to be soluble with Urea but not hexane as both Urea and water are polar while hexane is not. Test results: The test predictions were correct. The water and hexane remained separated when combined, and the urea did not dissolve when in the water. Part 2:
